摘要
A highly efficient and stable photocatalyst Ag/Ag3PO4 was prepared by the ion-exchange process between AgNO3 and Na2HPO4 and subsequently light-induced reduction route. The diffuse reflectance spectra (DRS) indicated Ag/Ag3PO4 had strong absorption in UV and visible-light regions. The composite showed excellent visible-light-driven photocatalytic performance. It can decompose organic dye within several minutes and still maintain a high level activity even though used five times. It is considered that this excellent performance results from the surface plasmon resonance of Ag nanoparticles and a large negative charge of PO43- ions. (C) 2011 Elsevier B.V. All rights reserved.
