g-C3N4/TiO2@Ag复合材料的制备及可见光催化性能研究
Study on preparation and photocatalytic performance of g-C3N4/TiO2@ Agunder visible light
摘要
Abstract
The composite materials(g-C3N4/TiO2@ Ag)are prepared with g-C3N4and Ag particles on the surface of TiO2microspheres as material using ultrasonic mixing.The materials are characterized by FT-IR,XRD,XPS,SEM,DRS,UV-Vis and PL.The photocatalytic activities of g-C3N4/TiO2@ Ag are tested by photocatalytic degradation of methylene blue(MB)solution under visible light.It is found that degradation rate of MB is 97.3% by g-C3N4/TiO2@ Ag and more efficiently than TiO2@ Ag(65.6%)and g-C3N4/TiO2(89.7%).It may be due to the existence of high photogeneratede --h+pairs charge separation.关键词
