| Abstract: | In this study, we synthesized Tb/Tourmaline/TiO2 nano tubes (NTs) through a solgel-hydrothermal method. The as-prepared samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, Raman spectromicroscope, scanning electron microscopy, transmission electron microscopy and UV-vis diffuse reflectance spectroscopy. The resulting Tb/Tourmaline/TiO2 NTs exhibited higher photocatalytic activity than pure TiO2 and TiO2 nano particles (NPs) in the degradation of menthyl orange under UV-light. Results revealed that doping rare earth element Tb could narrow the wide band gap of TiO2 and tourmaline could trap the photogenerated electron of TiO2 to inhibit the recombination of photogenerated electron-hole pairs. |
