The artificial leaf, bio-mimetic photocatalysis

Learning from the concepts used by green plants, an efficient and stable molecular photovoltaic cell based on the dye sensitization of mesoporous oxide films has been developed. The discovery of this photocatalytic device has opened up a realm of other applications, including spin-offs in the field of redox catalysis, intercalation batteries, nanocrystalline electronic junctions, and display technology.
