Abstract
Several processes in the pharmaceutical industry require large amounts of water that
inevitably are contaminated. Pharmaceuticals are often not completely removed in
sewage treatment plants and, therefore, are emitted into receiving water systems.
Recently, the use of advanced oxidation processes (AOPs) for complete destruction of
contaminants has been popular. AOPs are based on the production of reactive species
such as hydroxyl radicals that oxidized a wide range of organic pollutants quickly and
non-selectively.AOPs include photocatalytic systems like the combination of
semiconductor and lighting, and oxidants. Photocatalytic process as anenvironmentally
friendly process has considerable advantages over some existing technologies;can be
carried out under ambient conditions (atmospheric oxygen is used as oxidant and solar
light can be used as light source) and usually leads to complete mineralization of
organic pollutants into CO2 and H2O. This study focuses on the removal of the
pharmaceutical Atenolol (ATL) by TiO2photocatalysis. Operating factors such as initial
concentration, photocatalyst dosage, and pH solution were investigated in order to
evaluate the extent of mineralization.
Keywords: Pollution, Photocatalytic, Degradation, Atenolol, TiO2.

Application of Advanced Oxidation Processes (AOP) for the removal of toxic pollutants from water has been receiving increasing attention in recent times. Photocatalysis using semiconductor oxides is one such AOP which is being investigated extensively for the degradation of dyes in effluent water. This paper reports our findings on the sunlight induced photocatalytic removal of the hazardous xanthene dye Rhodamine B from water, mediated by TiO2 and ‘platinum deposited TiO2’ (Pt/TiO2).Unlike in the case of photocatalytic degradation of many organic pollutants which are driven by UV light, Rhodamine B can be removed in presence of TiO2 even by visible light. Pt/TiO2 is ~5 times more active than TiO2 alone for the solar photocatalytic degradation of the dye, which is attributed to extension of the absorption of light to the visible range and retardation of the recombination of photogenerated electrons and holes. The dye itself can absorb visible light and act as a photo sensitizer to activate TiO2. The effects of various parameters such as catalyst loading, concentration of the dye, pH, Pt concentration in Pt/TiO2, externallyadded H2O2 etc on the adsorption and /or degradation of the dye are evaluated. The degradation of the dye proceeds through intermediates and complete removal of Total Organic Carbon (TOC) is achieved many hours after the decolorisation of the dye. The rate of degradation decreases beyond a critical concentration of the dye, possibly due to reduction in the path length of photons in deeply colored solution. The higher degradation in alkaline pH is explained in terms of the ionization state of the catalyst surface and the enhanced adsorption facilitated by the electrostatic attraction between the negatively charged catalyst surface and the zwitter ionic form of the dye. H2O2, upto a critical concentration, accelerates the degradation. The observations are critically analysed and suitable mechanism for the photocatalytic mineralisation of RhB is proposed.

Talk given in Utrecht, The Netherlands, August 24, 2019 Title: Atomic layer deposition: Bridging semiconductors to catalysis and beyond Abstract: This talk will briefly explain the fundamentals of atomic layer deposition (ALD), view key historical turning points of the technique, and attempt to look into the future of ALD in the field of catalysis. ALD, a thin film growth method based on repeated self-terminating gas-solid reactions of compatible compounds, has become known as an enabler of Moore’s law and is today commonplace in the manufacturing of semiconductor devices. Currently, ALD is seen as highly promising for the controlled preparation of heterogeneous catalysts, testified e.g. from the number of reviews that appear on the topic. ALD can be used to grow films or nanoparticles and even single sites, and it can be similarly applied on powders, engineered 3D structures, and flat model catalysts.

(INVITED) Fundamentals of atomic layer deposition: an introduction (“ALD 101”) Riikka L. Puurunen, Aalto University School of Chemical Engineering, Department of Chemical and Metallurgical Engineering, AVS 21st International Conference on Atomic Layer Deposition (ALD 2021), Virtual Meeting 27.6.-30.6.2021. Tutorial Session 27.6.2021 ABSTRACT: Atomic layer deposition (ALD) has become of global importance as a processing technology for example in semiconductor device fabrication, and its application areas are continuously expanding. The significance of ALD was highlighted e.g. by the recent (2018) Millennium Technology Prize. Tens of companies are offering ALD tools, and thousands of people are involved in ALD R&D globally. A continuous need exists to educate new people on the fundamentals of ALD. While ALD for manufacturing may be regarded mature, as a scientific field, ALD—in the author’s view—is developing. For example, understanding of the early history of ALD is evolving, related to the two independent inventions of ALD under the names Atomic Layer Epitaxy in the 1970s and Molecular Layering in the 1960s [1-4]. Also, significantly varying views exist in the field related to the description and meaningfulness of even some core ALD concepts [5]. The purpose of this invited “ALD 101” tutorial is to familiarize a newcomer with fundamentals of ALD. The presentation largely follows the organization of a recent encyclopedia chapter on ALD [6]. Surface chemistry concepts will be introduced, such as ideal ALD from repeated, separate self-terminating (saturating and irreversible) reactions; growth per cycle in ALD; various monolayer concepts relevant to ALD; typical classes of surface reaction mechanisms and saturation-determining factors; growth modes; and ways to describe growth kinetics. Concepts, where differing views exist in the field and which thus need special attention, are pointed out. Typical deviations from the presented ideality are discussed. For continuous education, a collaborative OpenLearning website on ALD is under construction [7]. Many of the images used in this tutorial—and in Refs. 6 and 7—are available in Wikimedia Commons [8] for easy and free reuse. To contribute to collective learning of the early history of ALD, the open-science effort Virtual Project on the History of ALD [4] still welcomes new volunteer participants. [1] E.

Abstract With the growing number of industries there are large volumes of wastewater generated every day. Pulp and paper mills are highly polluting as they release effluents containing organic pollutants, and high levels of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). Even though well-established processes exist to treat these effluents, there are only a few processes which are energy efficient. Conventional treatment methods are not effective for the degradation of toxic organic pollutants, hence other treatment techniques are necessary. One of the recent developments in this field is the Advanced Oxidation Process (AOP). Solar photocatalysis is a type of AOP which utilises UV light to activate semiconductor photocatalyst in order to produce highly reactive radical species. TiO2 is a widely used catalyst for this purpose, to oxidise or reduce the organic pollutants in industrial wastewater. However, photocatalysis using visible light has been receiving increased attention hence, modification of TiO2 is necessary for its enhanced response to visible light. There are many methods for modifying TiO2, such as doping and photo-sensitisation. This study focusses on the modification of TiO2 using the method of dye-sensitisation (photo-sensitisation) with the dyes rhodamine B and methylene blue. Solar photocatalytic experiments were carried out for the degradation of pulp and paper wastewater, at different conditions like varying catalyst loading (500mg, 600mg, 750mg and 1000mg of catalyst for 300ml of aqueous wastewater) and effluent concentration (20ml, 25ml, 30ml and 35ml of wastewater). Preliminary tests were done to determine the best conditions for photocatalytic degradation, and these were applied for final tests.

Presentation at the AVS 20th International Conference on Atomic Layer Deposition (ALD 2020) featuring the 7th International Atomic Layer Etching Workshop (ALE 2020), online, 29.6.-1.7.2020. Authors: Riikka L. Puurunen and J. Ruud van Ommen Abstract text: Atomic layer deposition (ALD) has become of global importance as a fundamental building block for example in semiconductor device fabrication, and also gained more visibility (e.g., the Millennium Technology Prize 2018). In recent years, the number of ALD processes has increased, new groups have entered the field, and fundamental insights have been gained. At the same time, significantly varying views exist in the field related to the description and meaningfulness of some core ALD concepts. Open, respectful but critical scientific discussion would be needed around these concepts - for example at this AVS ALD/ALE conference, the world’s largest conference on ALD. The discussion on terminology of ALD that started in the 2005 surface chemistry review [1] is continued in this contribution, taking into account recent progress reported in leading reviews such as Ref. 2. We start by considering the concept of “ideal ALD”. How should it be defined so that the well-recognized practical benefits of ALD are maintained, while no unnecessary utopian requirements are created? We propose that the repetition of well-separated saturating, irreversible chemisorption reactions (which by definition saturate at a monolayer of the chemisorbed species) is sufficient to reproduce the benefits of ALD. A requirement of “full monolayer growth” (of the ALD-grown material), progressed e.g. in numerous cartoons of ALD, is not needed. There should also be no reason to expect a constant growth per cycle (GPC) within the ALD window (the saturating chemistry is typically weakly temperature dependent), although such a scheme is repeatedly reproduced in the literature. Other fundamental concepts will be pointed out, where mix-ups have been created. For example, although the GPC (or etch per cycle in Atomic Layer Etching) is a saturation-related concept and not a time-related kinetic parameter, Arrhenius plots have been sometimes created to extract “activation energies” of some process from these “growth/etch rates (per cycle)”. Also, “Langmuir adsorption” has been adopted as a way to model ALD in a simplified, lumped way. Notably, Langmuir adsorption assumes no interaction between adsorbed species, contrasting some recent discussions of “cooperative effects” in ALD. Also, concepts of “adsorption isotherm” and amount adsorbed vs. time (“saturation curve”), although fundamentally different, have been mixed. We hope that the discussion on the fundamentals of ALD will be intensified, and that the discussion will help the field progress and flourish in the future. [1] Puurunen, J. Appl. Phys. 97 (2005) 121301. [2] Richey, de Paula, Bent, J. Chem. Phys. 152 (2020) 040902.

Abstract of the presentation: Atomic layer deposition (ALD) is a thin film growth method generally applicable for the growth of conformal, highquality inorganic material layers down to the nanometer thickness range. ALD is indifferent to the morphology of the underlying substrate and covers even most complex 3-D shapes with a uniform film; as a consequence, ALD is used in an ever-increasing field of applications from catalysts to photovoltaics to microelectronics and beyond. ALD belongs to the general class of chemical vapour deposition (CVD) techniques. The speciality of ALD is the use of repeated self-terminating (saturating, irreversible) gassolid reactions of at least two reactants for the film growth; ALD is therefore non-continuous in nature, as opposed to the continuous CVD processes. In this presentation, I will discuss some challenges related to understanding the surface chemistry of ALD. The commonly-used trimethylaluminium-water ALD process to deposit Al2O3 is used as case example, as it is often presented as model case for ALD. I will also discuss the characteristics of ALD film conformality, as detected by using microscopic lateral high-aspect-ratio structures ("VTT μLHAR") [J. Vac. Sci. Technol. A 33, 010601 (2015)]. Here, the gap height is in the range of 100 nm's and the aspect ratio (AR) can be extremely challenging, e.g. up to 25 000:1. Finally, I will briefly introduce the on-going international volunteer-based Virtual Project on the History of ALD (http://vph-ald.com), where new participants are still welcome. Acknowledgement: The author thanks Finnish Centre of Excellence in Atomic Layer Deposition for funding.

Sodium hypochlorite (NaClO) is regularly used as a disinfectant or a bleaching agent because of its high efficiency against many bacteria and viruses present in seawater along with its cheaper cost. Now a days, with the increase in the environmental concerns concerning the use of chlorination for the disinfection or bleaching of treated water related to the formation of potentially harmful chloro-organic by products through reactions with natural organic matter (NOM), it is preferred to implement a process with environmentally friendly chemicals for water treatment processes. About This report aim to study the possibility of reducing the inorganic carbon present in seawater by oxidization reaction of seawater with TiO2 and H2O2. Investigated and a comparison between thin film method and suspension method with a reactor system in conjunction with a light concentrating system has been done.

Objective of this paper is to produce hydrogen which is an ideal fuel for the next generation because it is abundantly available in nature, energy efficient and clean. Wide varieties of technologies are available to produce hydrogen but only few of them are considered environmental friendly. Solar water splitting via photo catalytic reaction is one of them which have attracted tremendous attention. In this paper we are working on hydrogen production via solar splitting. Photo catalytic water splitting is one of the promising technologies to produce pure and clean hydrogen. Since it is reasonable having low process cost and has a small reactor, it can be made for house hold application and hence has a huge market potential. Generation of hydrogen under visible irradiation is the main area of work. Based on the literature reported here, visible irradiation can be achieved by doping of TiO2 with metal or non-metal. We have used Fe doping to increase the efficiency. The result indicates that Fe doped sieves produce more hydrogen than the normal TiO2 coated sieve and the efficiency can be increased if we increase the number of doped sieves and surface area.

Natural dye-sensitized solar cells (NDSSCs) have gained considerable attention in the field of solar energy due to their simple fabrication, good efficiency, and low production cost. Natural dyes are environmentally and economically superior to ruthenium-based dyes because they are nontoxic and cheap. However, the conversion efficiency of dye-sensitized solar cells based on natural dyes is low. One way to improve the DSSC performance is to enhance the absorptivity of extracted natural dyes. We investigated the influence of various factors in the extraction process, such as utilization of different extraction approaches, the acidity of extraction solvent, and different compounds of solvents on the optical absorption spectra. It was found that we could considerably enhance the optical absorptivity of dye and consequently the performance of DSSC by choosing a proper mixture of ethanol, methanol and water. In this study, a photo electrode using ZnO doped TiO2 nanoparticles was prepared by sol-gel method. In this paper we investigate the optical absorption, functional group, surface morphology and elementary composition of pure TiO2, ZnO doped TiO2 nanoparticles and opuntia prickly pear dye extract by using UV-Visible, PL-Studies, FT-IR, FE-SEM and EDS analysis. Finally photocurrent-voltaic characterization of nanocrystaline natural dye solar cell using I-V studies. It was found that the levels of short-circuit current (Jsc), open-circuit voltage (Voc), fill factor (FF) and overall conversion efficiency (η).

Abstract:The ability of high-energy ionizing radiation has been demonstrated for environmental remediation processing. γ-rayswere applied to treat a solution of 2-mercaptobenzothiazole (2-MBT). 2-MBT (125 µM) was decomposed and mineralized by the γ-radiation. The absorbed doses for 50 and 90% 2-MBT degradation were 0.170 and 0.650 kGy, respectively. Organic by-products were almost fully mineralized when high-absorbed doses in the range of 5-60 kGy were applied. Sulfate radicals (SO4 ●– ) produced through the rapid reaction of persulfate ions (S2O8 2– ) with hydrated electrons(eaq − ; keaq − /S2O8 2– = 1.1 × 1010 M −1 .s−1 ) had a significant effect on the 2-MBT mineralization yield. Because of 2-MBT decomposition,sulfate ions (SO4 2− ) were formed, and thepH and dissolved oxygen concentration were decreased. The degradation efficiency decreased when HCO3 –was added to the 2- MBT solution. No significant effects of NO3 – and Cl– ions on 2-MBT radiolytic eliminationwere observed

Abstract of Applied Sciences and Engineering, 2016, Vol.9 DOI: 10.18488/journal.1001/2016.9/1001.9 9th International Scientific Conference on Applied Sciences and Engineering 6-7 June 2016 Nippon Hotel, İstanbul-Turkey Conference Website: www.scihost.org 5 Paper ID: 05/16/ 9 th ISCASE Photocatalytic Degradation of Atenolol by Using Tio2 Catalysts under Solar Irradiation Madjene.

H3 --- Aoudjit .L4 1 Unité de Développement des Equipements Solaires, UDES, Centre de Développement des Energies Renouvelables, CDER, 42415, Tipaza, Algérie ; Laboratoire de Génie de la Réaction, Faculté de Génie Mécanique et Génie des Procédés (USTHB), BP 32, Alger, Algérie 2 Laboratoire de Génie de la Réaction, Faculté de Génie Mécanique et Génie des Procédés (USTHB), BP 32, Alger, Algérie 3,4 Unité de Développement des Equipements Solaires, UDES, Centre de Développement des Energies Renouvelables, CDER, 42415, Tipaza, Algérie Abstract Several processes in the pharmaceutical industry require large amounts of water that inevitably are contaminated. Pharmaceuticals are often not completely removed in sewage treatment plants and, therefore, are emitted into receiving water systems. Recently, the use of advanced oxidation processes (AOPs) for complete destruction of contaminants has been popular. AOPs are based on the production of reactive species such as hydroxyl radicals that oxidized a wide range of organic pollutants quickly and non-selectively.AOPs include photocatalytic systems like the combination of semiconductor and lighting, and oxidants. Photocatalytic process as anenvironmentally friendly process has considerable advantages over some existing technologies;can be carried out under ambient conditions (atmospheric oxygen is used as oxidant and solar light can be used as light source) and usually leads to complete mineralization of organic pollutants into CO2 and H2O. This study focuses on the removal of the pharmaceutical Atenolol (ATL) by TiO2photocatalysis. Operating factors such as initial concentration, photocatalyst dosage, and pH solution were investigated in order to evaluate the extent of mineralization. Keywords: Pollution, Photocatalytic, Degradation, Atenolol, TiO2.
