采用水热法在140 °C下反应23 h制备了TiO 2纳米管(TNT)。采用浸渍法制备了V2 O 5/TNT(VTNT)催化剂。VNTs的光催化效率远高于负载在TiO 2上的VNTs,且具有良好的耐水性和耐硫性。BET、TEM、XRD、NH3-TPD和EPR等表征结果表明,V2 O 5在TNT上分散良好,有利于NH3的吸附,促进V5+向V4+的转化,有利于在NH3和O2存在下形成氧空位和超氧自由基,从而提高了VTNT的催化活性。
TiO2 nanotubes (TNT) were prepared by hydrothermal method at 140 °C for 23 h. The V2O5/TNT (VTNT) catalysts were obtained by impregnation in NH4VO3 solution. The VTNTs exhibited much higher denitration efficiency than those supported on the raw TiO2, and satisfactory resistance to water and sulfur. Results from BET, TEM, XRD, NH3-TPD and EPR verified that V2O5 was dispersed well on TNT, thus favoring NH3 adsorption, promoting the transformation from V5+ to V4+, conducing to the formation of oxygen vacancies and superoxide radicals in the presence of NH3 and O2, and then resulting in the high catalytic activity of VTNTs.
