Abstract

Sheet-on-sphere structured Ag/AgBr@InVO4 heterojunctions were prepared via a precipitation–photoreduction method. Compared with pure InVO4 and Ag/AgBr, the Ag/AgBr@InVO4 photocatalysts displayed excellent photocatalytic performance for degradation of rhodamine B (RhB) under visible light (λ > 420 nm). Moreover, the Ag/AgBr@InVO4 sample with 30 wt% Ag/AgBr loading showed the best photocatalytic efficiency. The excellent photocatalytic activity of Ag/AgBr@InVO4 photocatalysts could be responsible for enhanced visible-light absorption and efficient anti-combination of photo-generated electrons and holes through the Ag/AgBr@InVO4 heterostructure.
