CN-Ag/AgI/γ-Al_2O_3 was successfully prepared by coupling carbon nitride( CN) with Ag/AgI/γ-Al_2O_3 via a thermal polymerization method,which was then characterized by means of X-ray diffraction( XRD),X-ray photoelectron spectroscopy( XPS),Transmission electron microscopy( TEM)and UV-vis diffuse reflectance spectra( UV-vis DRS). The effect of CN on the photocatalytic activity and stability was then investigated by degrading MO under visible light irradiation. The results indicated that the shapes and sizes ...
1引言(Introduction)光催化技术作为一种新型、绿色的环境污染治理技术,可以有效地去除水中难降解有机污染物,在水处理中具有广阔的应用前景(Zhang et al.,2015;Hou et al.,2013).在各种光催化材料中,贵金属纳米复合材料因具有表面等离子体共振(plasmon)效应,可以高效地利用可?
