Preparation of Y-Ce Doped with TiO_2 Photocatalyst in Microwave Ionic Liquids and Microwave Enhanced Photocatalytic Activity

摘要

Y and Ce co-doped TiO_2 photo-catalysts were synthesized by microwave drying method and sol-gel method with room temperature ionic liquid as a reaction medium. The purpose of the experiment was order to improve the photo-catalytic activity and accelerate the degradation of pollutants. The structure and morphology of TiO_2-Y-Ce were characterized with XRD, IR and SEM. The photo-catalytic activity was respectively investigated by microwave irradiation (MW) and ultraviolet irradiation (UV) and microwave irradiation with ultraviolet irradiation (MW-UV) with the photo-catalytic degradation of methyl orange and phenol solution as simulated pollutants. The results showed that the TiO_2-Y-Ce catalysts prepared at the optimum condition had higher photo-catalytic activity.
