ZnInS-based multi-interface coupled photocatalyst for efficient photothermal synergistic catalytic hydrogen evolution.

Photothermal synergistic catalysis is a novel technology that converts energy. In this study, ZnInS with S-vacancy (ZIS-Vs) is combined with Nickel, Nickle Oxide and Carbon Nanofiber aggregates (Ni-NiO@CNFs) to create a multi-interface coupled photocatalyst with double Schottky barrier, double channel and mixed photothermal conversion effect. Theoretical calculation confirms that the Gibbs free energy (ΔG) of the S-scheme heterojunction in the composite material is -0.
