	1	Synthesis of Gd-N Codoped Porous TiO2 Photocatalyst and Its Enhanced Photocatalytic Activities显示文摘Visible-light-active Gd-N codoped porous TiO2(Gd-N-TiO2) photocatalyst was fabricated by an evapora-tion-induced self-assembly route using surfactants as structure-directed agents. As-prepared samples were characte-rized by X-ray diffraction, field-emission scalming electron microscopy, transmission electron microscopy(TEM),X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller(BET) method, and ultraviolet-visible absorption spec-troscopy. The results indicated that synergistic reaction occurred when codoping with Gd^3+ and N, which enhancedthe light absorption properties of TiO2. Irregular worm-like particles with wide interparticle spaces were clearlyobserved by TEM. The average particle size of Gd-N-TiO2 decreased to ca. 8 nm because co-doping inhibited theparticles growth significantly. Thus, the specific surface area of Gd-N-TiO2(198.7 m^2/g) was higher than that ofDegussa P25 TIO2(50 m^2/g). Gd-N-TiO2 exhibited a high photocatalytic activity toward methyl orange degradationunder UV-Vis or visible-light irradiation. The Gd-N-TiO2 catalyst also presented a stable performance without losingactivity after four successive photocatalytic experiments. The facile synthesis and excellent activity of Gd-N-TiO2indicated its great potential as industrial catalysts for wastewater treatment.
