Abstract

Abstract : AgBr/Ag3 PO4 photocatalyst was synthesized using a facile coprecipitation method. The photocatalyst was characterized by X-ray powder diffraction (XRD), UV-Vis diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) surface areas, and photoluminescence (PL) technique. The activity of the photocatalyst was evaluated by the degradation of methyl orange (MO) and rhodamine B (RhB). The results showed that the prepared AgBr/Ag3 PO4 exhibited excellent performance and much higher photocatalytic activity than the single one under visible-light irradiation. The optimum mole ratio of Br/P in AgBr/Ag3 PO4 samples is 0.3. The prepared AgBr/Ag3 PO4 photocatalyst was transformed to Ag/AgBr/Ag3 PO4 system with excellent property and good stability in the photocatalytic process. The possible mechanisms of the enhanced photocatalytic activity for the AgBr/Ag3 PO4 were also discussed in detail.
