摘要: 采用微波辅助合成方法将WO3固载到金属有机骨架MIL-101(Cr)上，借助于沉积沉淀–光还原方法将Ag/AgCl和WO3/MIL-101复合在一起，制备出Ag/AgCl@WO3/MIL-101可见光催化剂。利用FT-IR、XRD、UV-Vis-DRS和XPS测试技术对该催化剂进行了表征。结果表明，Ag/AgCl和WO3的引入没有改变MIL-101的结构，催化剂在可见光区有强烈的光吸收。当WO3的负载量为0.3(w)%，Ag的负载量为3.4(w)%时，Ag/AgCl@WO3/MIL-101对70 mL 20 mg/L的罗丹明B溶液的降解率达到100%，并且该催化剂具有较好的稳定性。
Abstract: Tungsten oxide (WO3) was supported on MIL-101(Cr), affording a hybrid material WO3/MIL-101 by a microwave-assisted deposition method. Then, the plasmonic Ag/AgCl@WO3/MIL-101 catalyst was prepared by the deposition-precipitation-photoreduction method and characterized by FT-IR, XRD, UV-Vis-DRS and XPS techniques. It was found that the structure of MIL-101 was well preserved after the introduction of WO3 and Ag/AgCl, which showed strong light absorption in the visible region. When the loadings of WO3 and Ag was 0.3(w)% and 3.4(w)%, Ag/AgCl@WO3/MIL-101 exhibited a high photocatalytic activity and good stability for the degradation of RhB under visible light irradiation.
