| 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 CdIn2S4@MIL-53-SO3Ni1/2, which is highly efficient on prompting water splitting for the production of H2 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 CdIn2S4@MIL-53-SO3Ni1/2 should be ascribed to coating suspended ion catalyst (SIC), consisting of redox-active NiII ions in the anionic pores of coordination network MIL-53-SO3−, on the surface of photoactive CdIn2S4, which endows photogenerated electron-hole pairs separate more efficiently for high rate production of H2 and selective production of highly value-added organic products, demonstrating great potential for practical applications. |
