Zn2+-SiO2-TiO2三元复合催化剂的制备及其光催化降解性能
Preparation and photocatalytic activity of ternary composite catalyst: Zn2+-SiO2-TiO2
摘要
Abstract
The ternary composite nanocomposite photocatalyst,Zn2+-TiO2-SiO2,was prepared by sol-gel method,which was characterized by DRS,FT-IR,XRD and SEM. The photocatalytic activities of nanocompos-ites were investigated for the degradation of Rhodamine B and Congo red as a probe under the illumination of UV and visible light. Compared with TiO2,Zn2+-TiO2 and SiO2-TiO2,the ternary nanocomposite photocatalyst of Zn2+-TiO2-SiO2 showed higher photodegradation,and the photodegradation rate of Rhodamine B (5 mg/L) and Congo red (10 mg/L) could reach 90% and 83% under sunlight respectively.关键词
