    • The design and synthesis of homogeneous catalysts for visible light-driven hydrogen production inspired by the active sites of [FeFe] Hydrogenases have been conducted in our groups during the past years. In this presentation, biomimetic active site models of [FeFe] Hydrogenases with different CO/P ligands as catalysts for electrochemical proton reduction will be discussed. Photo-induced electron transfer between photosensitizers and Fe2S2 catalysts in both intramolecular and intermolecular systems will be shown. Successful hydrogen production driven by visible light catalysed by related dinuclear Fe2S2 complexes in the presence of electron donor provides further progress for solar energy conversion into a fuel.
