摘　　要：采用界面反应法合成了一种表面负载Ag纳米颗粒的Ag@AgCl纳米棒复合物。通过IR、XRD、SEM、TEM、XPS等手段对所制备材料进行表征。结果表明,采用界面法可以在常温、常压下将纳米颗粒负载在Ag纳米棒上。对所制备材料的光催化性能进行研究,由测试结果可知,该纳米复合材料在可见光下催化亚甲基蓝(MB)的活性要明显优于二氧化钛(P-25),且光照15 min后MB的降解可达96%。研究结果将为银/卤化银体系材料的开发及在可见光光催化领域的应用提供新的思路。In this paper,an Ag@AgCl nanorods composites was prepared by using a simple interface reaction method.IR,XRD,SEM,TEM,XPS and other means were used to characterize the as-prepared materials.The results showed that the Ag nanoparticles could load on the nanorod at room temperature and atmospheric pressure by interface reaction method.The detection results of its photocatalytic properties showed that the Ag@AgCl nanorods composites displayed better activity than that of TiO_(2)(P-25).The results of this paper provided novel approach for exploiting and utilizing Ag/AgX materials in photocatalysis.
