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⁺,...
