Hydrogen (H2) has the potential to replace fossil fuels as clean energy carrier of future, particularly if it is produced by water splitting using visible light. Natural [FeFe]-hydrogenase ([FeFe]-H2ase) known catalyze reversible reduction protons H2 with remarkable activity under mild conditions. In this respect, artificial photosynthetic systems for production sunlight and [FeFe]-H2ase mimics have attracted much attention, great progress been made in recent years. This perspective paper...
