Effects of metal ion-doping on the characteristics and photocatalytic activities of TiO₂ nanotubes

Ion-doped TiO₂ nanotubes were synthesized via a hydrothermal method and characterized by transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and specific surface areas. The binding energies of Cu²⁺, V²⁺, and Zn²⁺ indicated that the doping ions existed as Cu²⁺, V⁵⁺,...

description Ion-doped TiO₂ nanotubes were synthesized via a hydrothermal method and characterized by transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and specific surface areas. The binding energies of Cu²⁺, V²⁺, and Zn²⁺ indicated that the doping ions existed as Cu²⁺, V⁵⁺, and Zn²⁺, respectively. With the increase of the calcination temperature, the intensity of the anatase phase decreased and the BET surface area decreased. The extent of anatase phase increased with the increasing the calcination temperature, and then decreased. The highest catalytic activity for the un-doped TiO₂ nanotubes was observed at a calcination temperature of 500 °C, with a Rhodamine B (RB) removal efficiency of 98.1%.
