4. POROUS MATERIALS
 A porous material containing pores (voids).
 pores are typically filled with a fluid.
 examples of porous materials include sponges,
and cork.

7. Mesoporous Materials
Introduction
 Meso a Greek prefix ‘ inbetween’’ the micro
and macro porous sytems.
 They possess high
 surface area 400-1000m2g
 large pore volume
 high stability 500-600

10. HISTORY

12. TYPES OF MESOPOROUS MATERIALS

13. OXIDES
 Mesoporous Oxides of
tantalum
niobium
titanium
zirconium

also have been reported.

15. Hard Templates

16. APPLICATIONS
 Diagnostics
 Drug delivery system
 Adsorbents
 Chromatography
 Sensors
 Catalysis

17. Diagnostics
 Chemical stability.
 Low toxicity
 Flourescent markers
 Drugs can be used to track the location of
therapeutic agents and their activity.

18. ADSORBENT
 Use as adsorbents for various gases, liquids and toxic
heavy metals.
 Based upon surface property
hydrophobic, hydrophilic

19. CHROMATOGRAPHY
 Large pore volume surface area pore-size
distribution of mesoporous silica, make it a good
candidate for size exclusion chromatography.
 As stationary phases.

21. DRUG DELIVERY SYSTEMS
 Drug efficiency.
 Drug carrier must be non-toxic and inert during the
treatment period.
 Silica based Mesoporous materials have great
relevance for such life science applications.

22. CATALYSIS

23. SENSORS
 Have great potential in the field of gas sensing.
 Act as active layers in gas sensors based on various
operating principles, such as capacitive, resistive, or
optical sensing.
