TiO2/石墨烯纳米复合材料制备及其光催化性能研究
Preparation and Photocatalytic Performance of TiO2/Graphene Nano-composite Material
摘要
Abstract
TiO2/graphene composite photocatalyst has been prepared by a facile liquid phase deposition method using titanium trifluoride and graphene oxide as the raw materials.The products were characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and UV-Visible analysis.It was found that the reduction graphene was covered with petal-like anatase TiO2 nanoparticles, which were more uniform and smaller in size.The photocatalytic activities were evaluated using the photocatalytic reduction of CO2.Photocatalytic reduction of CO2 with H2O in the aqueous phase is studied by using TiO2/graphene catalyst under UV irradiation.The results showed that the compostie exhibited significantly photocatalytic reduction activities and reaction products high selectivity, reaction 6 h methanol accumulated production for 3.43 mmol/L.Graphene effectively improved the photocatalytic activity and reaction efficiency of the semiconductor, and synergistic effect was obvious.关键词
