Preparation and Characterization of TiO_2 Nanotubes Decorated by CuO and CeO_2 Particles
|
摘要
A novel catalyst, TiO_2 nanotubes(TiO_2 NTs) composite decorated by CuO and CeO_2 particles, was prepared by a simple and cost-effective method. The TiO_2 NTs were fabricated by the hydrothermal method, and CuO and CeO_2 particles loaded onto TiO_2 NTs(CuO/CeO_2@TiO_2 NTs) were prepared by the water bath heating method. The CuO/CeO_2@TiO_2 NTs were investigated and characterized by transmission electron microscope(TEM), energy dispersive spectrometer(EDS), photoluminescence(PL), X-ray diffractometer(XRD) and ultraviolet-visible light diffuse reflectance spectrum(UV-Vis DRS). Both the p-n heterojunction formed at the p-CuO and n-TiO_2 interfaces and the highly induced electron transfer of CeO_2 can greatly promote the separation of electrons-holes. Therefore, CuO/CeO_2@TiO_2 NTs show enhanced absorption and have potential applications in photocatalysis.
