Preparation of ZnIn2S4 microsphere/{001}crystal surface TiO2 nanosheet/g-C3N4 ternary photocatalyst and its properties
摘要
Abstract
In order to improve the photocatalytic performance of g-C3N4-based photocatalyst,g-C3N4 was prepared by bak-ing method,and then g-C3N4 was modified with exposed{001}crystal surface TiO2 nanosheets and ZnIn2S4 mi-crospheres,and the ternary composite photocatalyst ZnIn2S4/TiO2 NS/g-C3N4 was successfully synthesized.The morphology,structure,composition,and optical properties of the obtained products were characterized by means of TEM,XPS,XRD,and UV-Vis.On this basis,the visible light catalytic mechanism of ZnIn2S4/TiO2 NS/g-C3N4 was analyzed.The results show that the absorption range of visible light can be expanded by introducing ZnIn2S4 into g-C3N4 system.After ternary composite,TiO2,g-C3N4,and ZnIn2S4 have close contact and strong interactions.Based on the matching of the band positions of TiO2,g-C3N4,and ZnIn2S4,photogenerated electrons and holes can be efficiently generated,separated,and transferred during photocatalysis to promote the photo-catalytic efficiency of the system.When the mass fractions of TiO2 and ZnIn2S4 are 30%and 60%,respectively,the photocatalytic activity of ZnIn2S4/TiO2 NS/g-C3N4 ternary composite photocatalyst is the best after 100 min of visible light irradiation,and about 100%of methyl orange can be degraded into inorganic small molecules.关键词
