MoS2/ZnO异质结纳米材料降解亚甲基蓝的光催化性能研究
Photocatalytic properties of MoS2/ZnO heterojunction nanomaterials for degradation of methylene blue
摘要
Abstract
In order to improve the ZnO light conversion efficiency,the heterojunction of MoS2 with low band gap was selected to improve the photocatalytic performance.ZnO nanorods were prepared by hydrothermal method,and MoS2/ZnO heterostructure nanocomposites were further prepared.The morphology,structure,and optical properties of the samples are characterized by scanning electron microscopy(SEM),X-ray powder diffracmeter(XRD),UV-Visible solid dif-fuse reflection tester(UV-Vis),and ultraviolet-visible spectrophotometer(UV-245).The re-sults show that the MoS2/ZnO heterostructure nanocomposite exhibited a rod-like structure,and the presence of a built-in electric field can effectively enhance the separation efficiency of photoge-nerated charge carriers,increase absorption in the visible light region,and thus improve the pho-tocatalytic performance.Under simulated sunlight(including UV band),the degradation rate of methylene blue by MoS2-15/ZnO nanocomposites reached 99%,which is 10%higher than that of pure ZnO after 60 min.关键词
