PVP-Assisted Synthesis and Enhanced Photocatalytic Activity of Ag/Ag₃PO₄Composites

Abstract:

In the present work, a highly active visible-light-driven Ag/Ag₃PO₄ photocatalyst was synthesized through a simple poly (vinylpyrrolidone) (PVP)-assisted precipitation method. It was found that the photodegradation activity of RhB over Ag/ Ag₃PO₄ is superior to pure Ag₃PO₄ due to the combination of Ag nanoparticles. Study of the photocatalytic mechanism revealed that the degradation of RhB under visible light irradiation over the as-prepared Ag/Ag₃PO₄ is mainly via the direct hole oxidation mechanism. The Ag/Ag₃PO₄ photocatalyst keeps a high level of activity even though it is used for five times.
