F/Ce掺杂Bi2WO6可见光光催化氧化甲基橙
Photocatalytic oxidation of methyl orange by F/Ce doping Bi2WO6 photocatalysts under visible light irradiation
摘要
Abstract
In the paper,F/Ce doping Bi2WO6 photocatalysts were successfully fabricated by one-pot simple hydrothermal method in order to enhance the separation efficiency of photo-induced electron-hole pairs of Bi2WO6· The as-prepared samples were characterized by XRD,SEM and DRS.The resuits showed that F/Ce doping Bi2WO6 has clear layered structure and can effectively improve the separation efficiency of electron-hole pairs and the Bi2WO6 of doped F and Ce caused red shift.The results showed that F/Ce doping Bi2WO6 had the highest photocatlytic activity under visible light irradiation.The main active substance is · OH.The degradation of methyl orange can get 97％ after reaction of 50 min.The photocatlytic activity of F/Ce doping Bi2WO6 increased by two times compared that with pure Bi2 WO6· The result can provide basic data for high concentration organic wastewater,especially the high efficient treatment of refractory organic pollutants.关键词
