Bi 2 WO 6 /TiO 2 纳米管异质结构复合材料的多模式下的光催化活性比较(英文)
发布时间：2023-08-26 01:22
以TiO2纳米管为模板,采用多组分自组装结合水热法制备Bi2WO6/TiO2纳米管异质结构复合材料。通过多种技术如X射线衍射(XRD),X射线光电子能谱(XPS),N2吸附-脱附,扫描电镜(SEM),高分辨透射电镜(HRTEM)和紫外可见漫反射吸收光谱(UV-Vis DRS)考察所制备样品的组成、结构、形貌、光吸收和电子性质。Bi2WO6纳米片或纳米粒子分布在TiO2纳米管上,形成异质结构。随后,通过在紫外、可见和微波辅助光催化模式下降解染料罗丹明B(Rh B)来评价复合催化剂的光催化活性。与TiO2纳米管和Bi2WO6相比,Bi2WO6/TiO2-35纳米管在多模式下表现出更优异的光催化活性。与紫外和可见降解模式相比,Bi2WO6/TiO2
