3. INTRODUCTION
• Nanotechnology makes impossible things into
possible.
• By using nanotech we can convert even the
carbondioxide into fuel.
• Carbondioxide is absorbed by using the
nanotech and converted it into methane fuel.

4. CO2 IN ATMOSPHERE
• The united nations world meterological organisation
has reported that CO2 level is increasing 2.2 parts per
million per year.
• In 2016 the CO2 level will surpass 400 parts per
million.
• Now the CO2 level is 350 parts per million in the
atmosphere.

5. RESEARCH FINDINGS
• Tree growth increases under elevated CO2 and
decreases under O3
• Carbon sequestration under elevated CO2 is
overestimated in models which do not consider
O3 impacts
• O3 reduces the protective coating of leaves and
damages leaf tissues

6. • CO2 reduces the damaging effects of O3 and O3
reverses growth stimulation by CO2
• Plant response to CO2 may be limited by N
availability or co-exposure to O3 or other
factors.
• Aspen and birch insects and diseases increase
under elevated CO2 and O3

7. EFFECTS OF CARBONDIOXIDE
•
•
•
•
•
Heat waves
Rising sea level
Changing weather patterns
Fresh water shortages
Ocean acidification

8. NANOTECHNOLOGY
• Nanotechnology is the manipulation of matter
on a atomic and molecular scale.
• Nanotech is the science, engineering &
technology conducted at nano scale which is
about 1 to 100 nanometers.

10. ROLE OF NANOTECH IN CO2
CAPTURE AND CONVERSION

11. METHODS OF CO2 CAPTURE
• Use of nanoporous membranes
• Development of nanomaterials to trap carbon
dioxide – MOFs

12. CAPTURE THROUGH
NANOPOROUS MEMBRANE
• Membrane operates with liquid on one side
and gas on another side
• Driving force – thermodynamic potential of
CO2
• Comprises of hollow fibres

13. METAL ORGANIC FRAMEWORK
o What is a MOF?
– Porous crystalline compounds forming 1,2 or 3
dimensional structures with the use of metal ions
– Consist of a metal ion and an organic molecule,
often called a ligand.
– Store gases like CO2 and use catalysts
to convert them into fuel

15. CO2 CONVERSION INTO
METHANE
• Methane –one of the most efficient
hydrocarbons at storing energy
• Nanosized Rhodium alumina catalyst does not
require energy, only small source of O 2, low
temperature and pressure.
• Other process includes use of nano-tubes
composed of titania and a co-catalyst.
• Co-catalysts include platinum and/ or copper

16. • CO2 and H2O passed through membrane
composed of titania nanotubes and co-catalyst,
which converts into methane, hydrogen gas
and oxygen in the presents of sunlight.
• Process could be recycled

17. BENEFITS OF METHANE
• An energy storage medium, which allows
convenient and safe storage and handling
• A readily transported and dispensed fuel,
including for internal combustion engines and
methanol fuel cells
• A feedstock for synthetic hydrocarbons and
their products currently obtained from oil and
gas resources

18. MAIN IMPLEMENTATION
• First it is implemented in Iceland and in many
parts of Europe.
• United states of America had planned to
produce 1 billion barrel capacity of fuel in a
year.
• Then it is implemented in south west of
Britain.

19. USES OF METHANE FUEL
• Mainly for vehicles.
• Cloth dryers.
• In industries for making bricks, ceramic tiles
and cement.
• Generating steam in boilers.
• Source of heat in glass making and food
processing.
• For cooking and water heaters.

20. CONCLUSION
•
•
•
•
Pollution free.
Produced from the waste.
Less expensive.
One of the green energy.
