Synergistic effect of oxygen vacancies and Ni particles over the ZnWO4/CdS heterostructure for enhanced photocatalytic reduction and oxidation activities

A hybrid photocatalyst of oxygen vacancies-decorated ZnWO 4 /CdS–Ni greatly boosts the photocatalytic reduction and oxidation activities, which is due to the Z-scheme heterojunction after introducing oxygen vacancies and bifunctional Ni particles.
