Abstract

A series of Z-scheme CdS-RGO-BiVO₄ catalysts were prepared and their photocatalytic activities of hydrogen production were measured in visible light region. The results indicated that the Z-scheme system CdS-RGO-BiVO₄ prepared by evaporation & photo-reduction method possessed the highest photocatalytic activity of H₂ production. The properties of CdS-RGO-BiVO₄ were affected by the loading order of GO, CdS content and CdS morphology. When GO was first combined with CdS, the CdS content was 80 wt% and the morphology of CdS was nanorod, the optimal Z-scheme system of CdS-RGO-BiVO₄ was obtained and its photocatalytic activity of H₂ production reached 563.7 μmol/h. Furthermore, the relationship between the activity and its properties of CdS-RGO-BiVO₄ was also discussed.
