Ag2S/Ag3VO4催化剂的制备、表征及其在光催化性能研究
Synthesis,Characterization and Photocatalytic Activity of Ag2 S/Ag3 VO4 Catalyst
摘要
Abstract
The novel composite Ag2 S/Ag3 VO4 was successfully prepared by in-situ ion exchange,and the photocatalytic degradation of Rhodamine B (RhB)under visible light irradiation was investigated. The as-prepared samples were characterized by scanning electron microscopy (SEM),transmission e-lectron microscopy (TEM),X-ray diffraction (XRD),UV-Vis diffused reflectance spectra (UV-Vis) and Fourier transform infrared spectra (FT-IR).The results indicate that after introduction of Ag2 S, the photocatalytic activity and stability of Ag3 VO4 are obviously enhanced.For 0.8% Ag2 S/Ag3 VO4 composite,RhB removal rate reaches 95.6% within 100min under visible light irradiation,and after fourth cycle,the photocatalytic degradation rate still reaches 75%.关键词
