Artificial Photosynthesis

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

Hydrogen used to produce electricity

hydrogen to produce :

1- to produce fertilizer

• 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

95% Certainty Humans are theCause of Climate Change !

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
