Abstract: The principle of artificial semiconductor Z-scheme and recent advance in its catalysts for photocatalytic water splitting for hydrogen production are reviewed,including photosystem I catalysts (PS1[H2]),photosystem II catalysts (PS2[O2]) and their mediators. Their effects in Z-scheme photocatalysis and mechanism of electron transfer of PS1[H2],PS2[O2] and their mediators are illustrated. A comparison of photo conversion efficiency among some of the reported Z-scheme systems is made. Future research on Z-scheme systems should be focused on the mechanism of electron transfer of Z-scheme systems without mediators,synthesis of non-noble metal co-catalysts and applications in photocatalytic reduction of carbon dioxide and photoelectrochemistry.

Key words: Z-scheme, photochemistry, photo conversion efficiency, hydrogen production, solar energy
