In this study, a novel BiOBr/HPW/Au photocatalyst was prepared via hydrothermal method followed by photo-reduction method. The characterization results indicated the successful introduction of HPW and Au in BiOBr. BiOBr/HPW/Au exhibited excellent photocatalytic activity in RhB degradation. The degradation rate constant of BiOBr/HPW/Au was 3.55 times higher than that of BiOBr. Radical scavenger experiments showed that ·O₂^- was the dominant reactive radical species. A possible mechanism of the enhanced photocatalytic activity was attributed to the synergistic effect of BiOBr, HPW and Au, which resulted in enhanced quantum efficiency and high light harvesting efficiency.
