Er3+∶Y3Al5O12/ZnO复合物的制备及其光催化性能的研究
Synthesis of photocatalytic Er3+ ∶Y3Al5O12/ZnO and research of its photocatalytic activity
摘要
Abstract
An upconversion luminescence agent,Er3+ ∶Y3Al5O12 mixed with the ZnO,for utilizing visible light was synthesized by using sol-gel method and the hydrothermal method,and it was charactered by XRD and SEM.As an example,the photocatalytic activity of the Er3+ ∶Y3Al5O12 mixed with the ZnO on the methyl orange was researched under the visible light irradiation.In addition,the influence of the calcine temperature、calcine time、the visible light irradiation time and intensity,dye initial concentration and amount of catalyst on the degradation rate of the methyl orange were investigated‘ The results revealed that the degradation rate increased significantly by adding upconversion luminescence agent Er3+ ∶Y3Al5O12,and the degradation rate was the best for the 1.00 g/L of the amount of catalyst.关键词
