纳米金属氧化物由于其特殊的结构和优异的化学性能，尤其是二氧化钛和二氧化钛复合纳米材料的制备和研究受到了广泛的关注。采用静电纺丝法和水热反应相结合的方法成功合成了三维多单元CuO/TiO2半导体薄膜。通过差热分析（TG-DTA）、x射线衍射（XRD）、透射电子显微镜（TEM）和扫描电子显微镜（SEM）对样品进行了表征，结果表明TiO2纤维的直径约为<100 nm；此外，CuO纳米颗粒或纳米板在TiO2纤维表面呈倾斜生长，形成了分层异质结构的多孔形态。通过罗丹明B降解测试了样品的光催化性能，样品对模拟污染物的降解表现出明显的催化活性。最后阐述了CuO/TiO2纳米纤维的光催化机理。
The preparation and research of nanometer metal oxides has drawn considerable attention because of their special structure and excellent chemical properties, particularly titania and titanium dioxide composite nanomaterials. A three-dimensional (3D) multiple-unit semiconductor CuO/TiO2 film was successfully synthesized by the combination of an electrospinning method and a hydrothermal reaction. The samples were characterized by differential thermal analysis (TG-DTA), X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM), which indicated that the diameter of TiO2 fibers was about <100 nm; moreover, the CuO nanoparticles or nanoplates were growing aslant on the surface of the TiO2 fibers, which led to the porous morphology for the hierarchical heterostructure. The photocatalytic property of the sample was tested via rhodamine B degradation and the sample showed the obvious catalytic activity for the degradation of the simulation of pollutants. Furthermore, the photocatalytic mechanism of the CuO/TiO2 nanofiber is expounded at the end of the study.
