【 摘 要 】

A novel magnetically recoverable core-shell Fe3O4@Ag3PO4/AgCl photocatalyst has been developed featuring fast magnetic separation, stability and high photocatalytic activity under simulated solar light. This novel core-shell photocatalyst exhibited high photocatalytic activity towards degradation of chlorsulfuron (ChS) under simulated solar light. The complete degradation of ChS over the Fe3O4@Ag3PO4/AgCl photocatalyst took only about 60min. As a result, the developed photocatalytic integrated microspheres can effectively degrade organic pollutants and can be easily recovered by a magnet, and reused at least five times without appreciable reduction in photocatalytic efficiency. Therefore, the Fe3O4@Ag3PO4/AgCl photocatalyst developed in this study is a promising alternative for degrading organic pollutants.
