Developing MOFs to produce sustainable fuels from solar light with ultrafast spectroscopy

Solar-to-chemical energy conversion is the ultimate goal for scientists in the field of energy generation. Generating chemical fuels based on solar energy, a virtually inexhaustible energy source, would solve the energy challenge. We can accomplish this by mimicking the natural photosynthesis in plants by artificial materials. However, the efficiency of this is still too low for practical implementation.

The main goal is to develop artificial photosynthetic materials capable of fast charge transfer, using (supra) molecular systems that can mimic natural photosynthesis more closely, rather than systems containing inorganic semiconductors. Therefore, nanoporous frameworks consisting of organic units that link inorganic clusters (metal-organic frameworks) that absorb light will be used, placing in the nanopores different reactive centres for photosynthetic conversions. The transfer of charges through the material will be followed at the ultrafast time scale.
