Objective
• What is photosynthesis
• What’s Artificial photosynthesis
• Why artificial photosynthesis
• How artificial photosynthesis
• Useful of artificial photosynthesis
• In nature, plants use photosynthesis to convert sunlight and carbon dioxide into oxygen and a carbohydrate food source
• Chlorophyll is a vital piece of this process. It captures the energy of sunlight and allow it to be used to power the complex chemical reactions inside the plant to create various forms of carbohydrate.
Artificial photosynthesis is a chemical process that replicates the natural process of photosynthesis, a process that converts sunlight,water, and carbon dioxide into carbohydrates .
2H2O (l) O2 (g) + 4H (aq) + 4e
What Is A Solar Fuel ?
An energy-rich chemical compound,
such as methanol or methane or
carbon monoxide, made from sunlight,
carbon dioxide and water through
artificial photosynthesis that is a
carbon neutral renewable green
alternative to fossil fuels.
Currently there are no known molecular or heterogeneous catalysts for the reduction of CO2 to fuels that have the combination of rates, over potentials, selectivities.
Fuel production
CO2 + 2H+ + 2e- ↔ CO + H2O
CO2 + 6H+ + 6e- ↔ CH3OH + H2O
• The car has a fuel cell that uses hydrogen and oxygen to produce water and electricity. Like BMW(Hydrogen 7) and Honda (FCX Clarity)
Hydrogen transport
Solving green house problemartificial photosynthesis has the potential to reverse global warming (because its processes involve taking in carbon dioxide and releasing oxygen) if manipulated for use on a large industrial scale
