Summary:AgBrO 3 /AgBr compound photocatalysts were prepared via a precipitation method and characterized by X‐ray diffraction, field emission scanning electron microscopy, ultraviolet–visible diffusion spectroscopy, and solid surface fluorescence trials. The photocatalytic performances and mechanism were also investigated. It was found the 2.5 wt.% AgBrO 3 /AgBr compound photocatalyst was most effective in dye degradation. The AgBrO 3 /AgBr showed degradation rate up to 94.5% in a 10 mg/L MO (Methyl Orange) solution and was still very stable after five cycles of reuse. The AgBrO 3 /AgBr photocatalysts could oxidize and decompose methyl orange molecules under visible light irradiation. The compounding largely improved the photocatalytic activity of AgBr. Photocatalytic mechanism experiments showed ·OH was the major active species.
