ZnFe2O4@Cu-MOF催化剂的制备及其光催化性能研究
Preparation and Photocatalytic Performance of ZnFe2O4@Cu-MOF
摘要
Abstract
In this paper,a novel composite photocatalyst ZnFe2O4@Cu-MOF was synthesized.The structure,morphology and thermal stability of the catalyst were characterized by FT-IR,XRD,SEM and TG.The photocatalytic degradation performance of the composite ZnFe2O4@Cu-MOF for organic dye methyl orange was studied.The possible mechanism of photocatalytic reaction was investigated on the basis of photoelectric characterization results and free radical burst experiments.The results showed that after 120 min of simulated sunlight irradiation,the degradation rate of 10 mg/L methyl orange aqueous solution by composite photocatalyst ZnFe2O4@Cu-MOF reached 78.68%,which was 2.59 times and 1.34 times that of single ZnFe2O4 and Cu-MOF,respectively.After four experimental cycles,the photocatalytic degradation of methyl orange by ZnFe2O4@Cu-MOF decreased by only 3.70%.The combination of ZnFe2O4 and Cu-MOF increases the catalytic active site,improves the utilization efficiency of visible light,and facilitates the carrier aggregation and rapid separation at the heterogeneous interface,which makes the composite photocatalyst has excellent photocatalytic activity and stability.关键词
