Synergistic Effect of Y Doping and Reduction of TiO₂ on the Improvement of Photocatalytic Performance.

ABSTRACT: Pure TiO₂ and 3% Y-doped TiO₂ (3% Y-TiO₂) were prepared by a one-step hydrothermal method. Reduced TiO₂ (TiO₂-H₂) and 3% Y-TiO₂ (3% Y-TiO₂-H₂) were obtained through the thermal conversion treatment of Ar-H₂ atmosphere at 500 °C for 3 h. By systematically comparing the crystalline phase, structure, morphological features, and photocatalytic properties of 3% Y-TiO₂-H₂ with pure TiO₂, 3% Y-TiO₂, and TiO₂-H₂, the synergistic effect of Y doping and reduction of TiO₂ was obtained. All samples show the single anatase phase, and no diffraction peak shift is observed. Compared with single-doped TiO₂ and
