Photocatalytic activity of novel AgBr/WO3 composite photocatalyst under visible light irradiation for methyl orange degradation

► AgBr/WO3 was prepared successfully by simple deposition-precipitation method. ► AgBr/WO3 displays good photocatalytic activity under visible light (λ > 420 nm). ► OH acted as active species are responsible for the degradation of MO.
