The demand and supply of energy will be a crucial question facing all societies in the coming years. Reasons behind this are the ever-increasing world population and the legitimate aspiration of developing countries to reach higher life standards. This issue gets even more complicated when we take into account the side effects arising from the extensive use of fossils fuels on our environment. A potential solution to this problem is to look at nature for inspiration. While photosynthesis is responsible for energy input into the biosphere, it uses only a small fraction of the solar energy that reaches the Earth’s surface. Indeed the amount of solar energy reaching the planet is so great that many scientists consider that its capture and usage provides the best long-term solution to the energy problem and the associated climate change crisis.
During photosynthesis, absorption of light initiates a series of energy and electron transfer processes that lead to the oxidation of water (eq. 1) in order to produce reducing equivalents that can then drive the reduction of either CO2 into higher carbohydrates (eq. 2), or protons into H2 (eq 3):
2 H2O + 4 hν -> O2 + 4 H+ + 4 e- (1)
nCO2 + 2n e- + 2n H+ -> (CH2O)n + n/2 O2 (2)
2 H+ + 2 e- -> H2 (3)
The use of water as a source of protons and electrons and light in order to produce clean fuels is one of the most important chemical challenges lying ahead. This task will span all fields of the physical sciences as we strive to develop systems that are capable of promoting the catalytic oxidation of water with sunlight as the sole energy input. Additionally, the resulting protons and electrons from this reaction must be collected for use in the formation of fuels. In this course we will discuss on different aspects for the elaboration of a supra-molecular assembly that can
- capture solar energy
- convert it to a charge separated state with charge accumulation in a vectorial fashion
- perform multielectronic catalysis, like oxidation of water, reduction of protons to H2 or reduction of CO2.
