Abstract
Abstract Photocatalytic water splitting coupled with the production of highly value‐added organic chemicals is of significant importance, which represents a very promising pathway for transforming green solar energy into chemical energy. Herein, we report a composite photocatalyst CdIn 2 S 4 @MIL‐53‐SO 3 Ni 1/2 , which is highly efficient on prompting water splitting for the production of H 2 in the reduction half‐reaction and selective oxidation of organic molecules for the production of highly value‐added organic chemicals in the oxidation half‐reaction under visible light irradiation. The superior photocatalytic properties of the composite photocatalyst CdIn 2 S 4 @MIL‐53‐SO 3 Ni 1/2 should be ascribed to coating suspended ion catalyst (SIC), consisting of redox‐active Ni II ions in the anionic pores of coordination network MIL‐53‐SO 3 − , on the surface of photoactive CdIn 2 S 4 , which endows photogenerated electron‐hole pairs separate more efficiently for high rate production of H 2 and selective production of highly value‐added organic products, demonstrating great potential for practical applications.
