摘要
采用简易的沉积-光还原的方法将Ag/Ag Cl纳米粒子负载到Bi2Mo O6微球上,制得Ag/Ag Cl/Bi2Mo O6异质结。分别采用XRD、SEM和UV-vis DRS对样品进行了表征。以罗丹明B(Rh B)为模拟污染物,考察样品的可见光光催化活性。结果表明,相比于Ag/Ag Cl和Bi2Mo O6,Ag/Ag Cl/Bi2Mo O6异质结的可见光催化活性明显提高,且Ag/Ag Cl负载量为40 wt%时,复合物的光催化活性最高。
Ag/AgCl/Bi2MoO6 heterojunction was prepared by loading Ag/AgCl nanopartictes on the surface of Bi2MoO6, microspheres through a facile deposition-photoreduction process. The as-prepared samples were characterized by XRD, SEM and UV-vis DRS. Rhodamine B （RhB） was selected as a model pollutant to evaluate the photocatalytic activity of the photocatalysts. The as-obtained Ag/AgCI/Bi2MoO6 photocatalysts exhibited much higher photocatalytic activity than Ag/AgCl and Bi2MoO6. The sample with 40 wt% Ag/AgCl showed the highest photocatalytic performance towards the degradation of rhodamine B.
