Preparation of Ag/CdS/MIL‐101(Cr) Composite by Dual Solvent Method and Its Photocatalytic Hydrogen Production

Abstract MIL‐101(Cr) with regular octahedron structure was synthesized by hydrothermal method, and CdS/MIL‐101(Cr) was prepared by solution titration. CdS was introduced into the surface of MIL‐101(Cr) matrix with large surface area and its pores to make it well dispersed and grow. On this basis, nano‐Ag was compounded, and the charge transfer rate was increased and the optical response spectrum of CdS was prolonged by using the localized surface plasmon resonance effect of noble metals. The results showed that under visible light irradiation, Ag/CdS/MIL‐101(Cr)‐0.6 ternary composite exhibited excellent photocatalytic H 2 generation rate (521.05 μmol/(g h), which was 1.9 times that of CdS/MIL‐101(Cr)‐0.4. This provides an idea for the synthesis of other high‐performance photocatalytic materials.
