| 摘 要： | 研究了碳纳米管担载的五氧化二钒（V2O5/CNTs）催化剂上NO低温选择催化还原反应（SCR）。与活性炭载体的催化剂作了对比，结果显示，在负载低含量V2O5时碳纳米管较活性炭显示了更好的催化能力，而且在SO2存在下，催化性能有更大幅度的提高。暂态反应实验显示，V2O5/CNTs 催化剂上NO选择催化还原反应遵循Eley Rideal机理，即反应发生于吸附态的NH3和气相或弱吸附的NO之间。

| Abstract: | In this article,low-temperature selective catalytic reduction(SCR) reaction of NO on carbon nanotube-supported vanadium(V2O5/CNT) catalysts was carried out.When compared with activated carbon as a support catalyst,carbon nanotubes with low load of V2O5 show excellent catalytic activity than that of activated carbon,and the catalytic activity of V2O5/CNT catalysts increases markedly in the presence of SO2.The transient reaction experiment shows that the reaction of V2O5/CNT catalyst for low-temperature SCR o... |
