Abstract

通過水熱方法合成了可見光響應的LaVO4/TiO2納米管,采用XRD,TEM,氮氣吸附-脫附以及表面光電壓譜對樣品進行了表征.以氣相甲苯為典型污染物,研究了制備樣品在可見光(λ>420 nm)條件下的光催化性能.實驗結果表明,LaVO4的復合使TiO2的粒徑減小,比表面積增大,光響應范圍向可見光偏移.光催化實驗結果表明,在可見光條件下,LaVO4/TiO2納米管降解甲苯的效率比其它樣品高,與純TiO2納米管相比,降解效率提高了47%. LaVO 4/TiO 2 nanotubes, which can response for visible light, were prepared by hydrothermal method, and characterized by TEM, XRD and N 2 adsorption-desorption measurements as surface photovoltage spectroscopy.The photocatalytic activity of the LaVO 4/TiO 2 nanotub evaluated by degradation of gaseous toluene under visible light (λ>420 nm) irradiation.The doped reduced the average crystal size, enhanced specific surface area and shifted the optical absorption the visible region of TiO 2.The photocatalytic activity of LaVO 4/TiO 2 nanotubes was increased by 4 pure TiO 2 nanotubes.
