钒酸铋/二氧化钛--石墨烯宽光谱复合光催化剂的制备及性能
Preparation and properties of BiVO4/TiO2--graphene composite photocatalysts with wide spectra
摘要
Abstract
BiVO4/TiO2- graphene ( BiVO4/TiO2- GR ) photocatalysts were prepared by a facile solvothermal method. The composite photocatalysts were characterized by X-ray diffraction, transmission electron microscopy, UV-Vis diffuse reflectance spec-trometry, and photoluminescence spectrometry. The photocatalytic activity was evaluated by degradation of methylene blue ( MB ) under simulated sunlight irradiation. It is found that the composite photocatalysts have a strong absorption peak in the 530-800 nm range of visible light. The introduction of graphene not only enlarges the absorption range of visible light, but also makes BiVO4 and TiO2 particles disperse uniformly in graphene sheets, and can capture and transfer the photogenerated charges, leading to an efficient improvement in photocatalytic activity.关键词
