摘要：
In this study, novel Ag@Ag3PO4 modified ZnSn(OH)(6) (ZSH) photocatalyst was prepared by a facile situ deposition and photo-reduction reaction method. Superior photocatalytic activities for dye and dye mixture degradation were achieved. Moreover, preferable photoelectric performances were verified by electrochemical tests. The introduction of Ag@Ag3PO4 on ZSH and surface plasmon resonance (SPR) effect played an important role in photoelectrons transferring, photogenerated electron-holes separation and photoactivity enhancement. Simple assembling method, good reusability, high photoelectric properties and multi-component, dyes wastewater treatment make it possible for practical industrial applications. (C) 2016 Elsevier B.V.
