Co–P bond effect on an MOF-derived Co9S8hollow polyhedron supported Ni2P co-catalyst for efficient photocatalytic hydrogen evolution

A novel and efficient Co 9 S 8 @Ni 2 P composite photocatalyst was successfully prepared by loading Ni 2 P on the surface of Co 9 S 8 , in which the formation of Co–P bonds accelerates electron migration and promotes photocatalytic reaction.
