Abstract

Novel composite photocatalysts, Ag@(Ag₂S/Ag₃PO₄), have been synthesized by controlled calcination and exhibited much higher activity than that of Ag₃PO₄, Ag₂S/Ag₃PO₄, Ag/Ag₃PO₄ and AgX/Ag₃PO₄ (X = Cl, Br and I) in degradation of rhodamine B. The excellent activity is ascribed to the synergistic effect between Ag and Ag₂S.
