脉冲沉积制备Cu2O/TiO2纳米管异质结的可见光光催化性能 = Visible light photocatalytic performance of Cu2O/TiO2 nanotube heterojunction composites prepared by pulse deposition

在用阳极氧化法制备有序排列TiO2纳米管阵列薄膜的基础上, 引入脉冲沉积工艺，成功实现了均匀、弥散分布的Cu2O纳米颗粒修饰改性TiO2纳米管阵列, 形成Cu2O/TiO2 纳米管异质结复合材料. 利用场发射扫描电镜(FESEM)、场发射透射电镜(FETEM)、X射线衍射(XRD)、X射线光电子能谱(XPS)和紫外-可见漫反射光谱(UV-Vis DRS)对样品进行表征, 重点研究了Cu2O/TiO2 纳米管异质结的光电化学特性和对甲基橙(MO)的可见光催化降解性能. 结果表明, Cu2O纳米颗粒均匀附着在TiO2纳米管阵列的管口和中部位置, 所制备的Cu2O/TiO2 纳米管异质结具有高效的可...
