钕负载二氧化钛-炭杂化气凝胶的制备及其光催化性能
Nd-doped TiO2-C hybrid aerogels and their photocatalytic properties
摘要
Abstract
Nd-doped TiO2-C hybrid aerogels with different Nd doping levels were prepared by a combined sol-gel and impregna-tion method. The microstructure,morphology and photocatalytic activities of the samples were investigated by XRD,SEM,FTIR, XPS, nitrogen adsorption and the photocatalytic degradation of methylene blue(MB) under UV irradiation. Results showed that the samples are composed of irregular-shaped nanoparticles and the Nd dopant inhibits their growth. The TiO2in the samples is anatase, the carbon is amorphous and Nd3+is in a Ti-O-Nd bond form. The samples had strong absorption in the ultraviolet region and exhibi-ted good degradation activity for MB in aqueous solutions under UV light. The best activity was achieved when the ratio of Nd to Ti is 3-4 wt%,in which case MB was completely degraded under UV irradiation for 160 min.关键词
