CdS decorated artificial leaf BiVO4/InVO4 for photocatalytic hydrogen production and simultaneous degradation of biological hydrogen production wastewater

Abstract CdS decorated artificial leaf BiVO4/InVO4 Z-scheme heterogeneous photocatalyst (BiVO4/InVO4 @ CdS) was synthesized for the first time by “Biological Template (BT)”-“Dipping Calcination (DC)”-“Successive Ionic Layer Adsorption and Reaction (SILAR)” method. The as-prepared BiVO4/InVO4 @ CdS exhibits excellent photocatalytic activity and stability for the degradation of biological hydrogen production wastewater and simultaneous production of hydrogen (H2), that can be attributed to its ascendant leaf-liked structure and Z-scheme heterogeneous composition. Furthermore, the possible mechanism of simultaneous H2 production and organic pollution oxidation in biological hydrogen production wastewater was proposed.
