![]() In this work, a series of BiOBr/BiOCl/AgBr ternary composite photocatalysts with excellent photocatalytic performance is synthesized by coprecipitation, and its photodegradation property in catalytic degradation of rhodamine B (RHB) dye under visible light irradiation is investigated. Silver bromide has strong photosensitivity but poor photocatalytic performance due to the serious recombination of photoelectron-hole pairs and the potential reaction between photoelectrons and silver ions. ![]() Bismuth compound BiOX (X = Cl, Br) is an excellent wide band gap semiconductor photocatalytic material but a greatly limited absorption of visible light. Photocatalytic technology is a green technology using solar energy, which plays an important role in environmental protection. ![]()
