1. ARTIFICIAL PHOTOSYNTHESIS

2. INTRODUCTION
What is future of energy
producing technology that
can be envisioned today
that will last for millennia
and can be implemented in
developing countries?

3. CURRENT ENERGY SOURCES
ADAM HILL, TED TALKS

4. CARBON EMISSION
SHORTAGE OF STORED ENERGY

5. ADAM HILL, TED TALKS

6. “THE ONLY ANSWER IS ARTIFICIAL
PHOTOSYNTHESIS”
PROBLEMS OF RENEWABLE ENERGY SOURCE
 STORAGE
 DISTRIBUTION IN LARGE
SCALE
 COST

8. GENERAL MECHANISM
1.LIGHT CAPTURE AND MOVING THE
ELECTRONS TO THE REACTION CENTRES.
2.SPLITTING WATER INTO HYDROGEN AND
OXYGEN.
3.REDUCING CARBON DIOXIDE.

14. KEY ISSUES:
COST OF CATALYSTS
THERMODYNAMIC BARRIERS
CORROSION

15. ADVANTAGES OF NiOx COATING
• Chemically stable, low susceptibility to
corrosion.
• Transparent and anti-reflective.
• Low cost
PREVENTION OF CORROSION
FINDINGS BY SUN K. et al.

16. MODERN APPROACH
“HETEROBIMETALIC CHEMISTRY”
ADAM HILL, TED TALKS

17. ADAM HILLS LECTURE, TED TALKS

18. ADAM HILLS LECTURE, TED TALKS

19. HOW CLOSE WE ARE?
 MANY SOLAR FUELS EXPERTS MAINTAIN THAT
THE RESEARCH HAS DECADES TO GO
 CONSIDERING THE CHALLENGES THEY MIGHT
BE RIGHT

20. HOW AMBITIOUS WE ARE?
COULD PRODUCE H2 FUEL AS WELL AS
REDUCE ATMOSPHEREIC CO2 LEVELS.
IT’S A WIN-WIN.
ALMOST EVERYTHING WE NEED REGARDING
ENERGY CONSUMPTION CAN BE PRODUCED.

21. CONCLUSION
“ WE ARE IN THE FIRST STEPS TOWARDS A
MACHINE THAT CAN DO WHAT PLANTS
DO WITHOUT ALL THE DRAWBACKS,
SOMETHING THAT CAN TAKE THE POSITIVE
ASPECTS OF RENEWABLE ENERGY
SOURCES AND COMBINE THEM WITH
POSITIVE ASPECTS OF CHEMICAL FUELS.”
