A Z-scheme CdS/BiVO photocatalysis towards Eriochrome black T: An experimental design and mechanism study.

The synergistic photocatalytic activity was obtained when CdS and BiVO nanoparticles (NPs) were coupled. The samples were characterized by XRD, FTIR, SEM-EDX, and UV-DRS techniques, and their pHpzc was also estimated. The crystallite size of the coupled sample was estimated at 37.
