Abstract Copper oxide (CuO) loaded titanium dioxide (TiO2) nanotube photocatalyst was synthesised using the facile hydrothermal method. The synthesised photocatalyst were characterised by X-ray diffraction (XRD), field emission scanning microscopy (FESEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS) to study their physiochemical properties. The photocatalytic activity of the photocatalysts was tested for carbon dioxide (CO2) photoconversion into fuels. CuO loaded TiO2 nanotube demonstrated higher CO2 conversion (100%) than TiO2 nanotube (72.20%) because of the former’s effective separation of photogenerated electron-hole pairs in the presence of CuO.

用于CO 2 光转化的高效CuO负载TiO 2 纳米管光催化剂

摘要 采用简便的水热法合成了负载氧化铜 (CuO) 的二氧化钛 (TiO2) 纳米管光催化剂。通过X射线衍射（XRD）、场发射扫描显微镜（FESEM）、透射电子显微镜（TEM）、高分辨透射电子显微镜（HRTEM）和X射线光电子能谱（XPS）对合成的光催化剂进行表征，以研究其理化性质。特性。测试光催化剂的光催化活性以将二氧化碳 (CO2) 光转化为燃料。负载CuO 的TiO2 纳米管表现出比TiO2 纳米管（72.20%）更高的CO2 转化率（100%），因为前者在CuO 存在下有效分离光生电子-空穴对。
