Pr3＋／TiO2催化剂的制备及光催化性能分析
Preparation of Pr3+/TiO2 photocatalyst and its photocatalytic performance
摘要
Abstract
The Pr3 +/TiO2 photocatalyst with different amounts of doped Pr3 + and calcination temperatures are synthesized by sol-gel method and characterized by XRD,FT-IR and SEM.Basic fuchsin experiment is chosen to evaluate photocatalyst activity.The results show that the synthesized samples are anatase TiO2 with the Pr3 + doped.While it has been found that rare earth interrupts the transformation from anatase to rutile.Photocatlytic experiment results show when the sample is calcined at 400 ℃,containing 0.2% Pr3 +/TiO2 and 1 mL 30%H2 O2 ,without lighting,and t =120 min,the degradation rate is 100%.关键词
