Mixed anion compounds such as oxynitrides and oxychalcogenides are potential photocatalysts for visible-light water splitting, because p orbitals of less electronegative anion(e.g., N3-, S2-)can form a valence band that has more negative potential than oxygen 2p orbitals. This article describes our recent progress in the development of new mixed anion-type photocatalysts for visible-light-driven water splitting.
