Ag/TiO2纳米催化剂的制备及性能
Preparation and properties of Ag/TiO2 nanoparticle catalyst
摘要
Abstract
Ag-TiO2 catalyst was prepared by the sol-gel method. The nanoparticles were characterized by means of X-ray diffraction (XRD),scanning electron microscopy (SEM),N2 adsorption-desorption isotherm (BET),and transmission electron microscopy (TEM). Degradation of methylene blue (MB) was studied at different doping contents and different calcination temperatures. The results showed that the specific surface areas of the samples increased and the transition from anatase to rutile were greatly inhibited when the calcinated temperatures was 800℃. Also the photocatalytic activity was found to increase after Ag was doped. When the calcinated temperature was 500℃ and 1% Ag doped TiO2 nanoparticles were irradiated under ultraviolet light,the degradation rate of MB reached 90% after 180min.关键词
