Preparation and Visible Light Photocatalysis of Graphite Carbon Nitride Composites
摘要
Abstract
The work aims to improve photocatalytic performance of graphite carbon nitride (g-C3N4). Graphene oxide (GO) and g-C3N4 were prepared by Hummers method and one-step semi-enclosed pyrolysis method respectively, then TiO2/g-C3N4, ZnO/g-C3N4 and RGO/g-C3N4 composites were fabricated in solvothermal method, thermal polycondensation method and im-pregnation chemical reduction method,respectively. The composite materials were characterized by X-ray diffractometer (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), UV-Vis diffuse reflectance absorption spectroscopy (UV-Vis DRS) and Fourier transform infrared spectroscopy (FTIR). Simultaneously, photocatalytic performance of the composites was evaluated based on degradation reaction of Rhodamine B (RhB). The g-C3N4 prepared in pyrolysis me-thod and made of melamine and urea exhibited higher photocatalytic activity than that made of pure urea. The introduction of TiO2, ZnO and RGO considerably enhanced photocatalytic activity of g-C3N4, and degradations rate of RhB rate was 95.6%, 95.0% and 78.1%, respectively. The RGO/g-C3N4 composite exhibited highest catalytic efficiency provided with 2.0 wt% RGO. Absorption intensity and electron conduction capability of the composites as well as photocatalytic performance in visible light are improved due to special band control advantage of g-C3N4and synergistic effect among TiO2, ZnO and RGO.关键词
