双金属位催化剂Ag-Ni/g-C3N4可见光催化降解亚甲基蓝
Carbon Nitride Bimetallic Ag-Ni/g-C3N4 Catalysts for Photocatalytic Degradation of Methylene Blue under Visible-light Irradiation
摘要
Abstract
The supported bimetallic Ag-Ni/g-C3N4 photocatalysts were generated by an in-situ reduction route, and the photocatalytic degradation of methylene blue under visible light illumination was investigated. The results indicate that the bimetallic Ag-Ni/g-C3N4 sample presents a better photocatalytic activity for methylene blue, compared to Ag/g-C3N4 and Ni/g-C3N4 samples. At the total loading mass of metal particles of 4.0%, the photocatalyst Ag(2)-Ni(2)/g-C3N4 sample with Ag/Ni mass ratio of 1:1 exhibits a superior degradation activity, and slightly deactivates after seven times. It can be ascribed to the synergetic effect between metallic Ag and Ni, which can greatly enhance the transfer rate of photo-induced carriers and effectively separate the photo-generated electron-hole pairs.关键词
