摘要:
采用原位离子交换法成功制备了新型复合催化剂Ag2S/Ag3VO4,并考察其在可见光照射下光降解罗丹明B的性能。通过扫描电镜(SEM),投射电镜(TEM),X射线粉末衍射仪(XRD),紫外可见漫反射(UV-Vis),红外光谱(FT-IR)等手段对所合成的复合材料进行表征。结果表明,与 Ag2S耦合后,Ag3VO4的光催化活性和稳定性得到明显提高。可见光照射100 min后,0.8% Ag2S/Ag3VO4复合催化剂对罗丹明B的光降解率达到95.6%,4次循环反应后仍能保持较高的光催化活性(75%)。
Abstract:
The novel composite Ag2S/Ag3VO4 was successfully prepared by in-situ ion exchange, and the photocatalytic degradation of Rhoda mine B(RhB)under visible light irradiation was investigated. The as-prepared samples were characterized by scanning electron microscopy(SEM),transmission electron 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 Ag2S, the photocatalytic activity and stability of Ag3VO4 are obviously enhanced. For 0.8% Ag2S/Ag3VO4 composite, RhB removal rate reaches 95.6% within 100 min under visible light irradiation, and after fourth cycle, the photocatalytic degradation rate still reaches 75%.
