Photocatalytic Hydrogen Evolution Coupled with Production of Highly Value‐Added Organic Chemicals by a Composite Photocatalyst CdIn2S4@MIL‐53‐SO3Ni1/2

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. A composite photocatalyst CdIn2S4@MIL‐53‐SO3Ni1/2, consisting of photoactive cadmium indium sulphide core and suspended ion catalyst MIL‐53‐SO3Ni1/2 shell, demonstrates high photocatalytic efficiency and stability in H2 evolution coupled with production of highly value‐added imines under visible light irradiation.
