Artificial Photosynthesis: Researchers Create Photo-Electrode for Hydrogen Production - FuelCellsWorks
CEA researchers have made a step towards the preparation of a lasting photo-electrode for hydrogen production. It is based on a hybrid architecture, based on a semiconductor interfaced with a molecular catalyst. The electrode contains only elements found in abundant quantities in the earth’s crust.
Hydrogen (H 2 ) is a promising fuel and a good means of storing renewable energies that it will subsequently restore by combustion with molecular oxygen (O 2 ) in fuel cells. Its carbon footprint will then be zero: this reaction only produces water! Green hydrogen can thus be produced from water and solar energy in a process mimicking photosynthesis. The sustainability of this future technology, however, rests on the development of new materials that are both active, stable and based on abundant and inexpensive elements.
