摘　　要：采用浸渍法制备了V2O5/TiO2催化剂,研究了V2O5/TiO2催化剂上NH3选择性催化还原NO的反应动力学,运用Eley-Rideal机理模型确定了相关的动力学参数,推导出本征动力学方程,得到反应的活化能为41.9 kJ/mol。V2O5/TiO2 Catalysts were prepared by an impregnation method. The reaction kinetics was stud ied on the selective catalytic reduction of NO with NH3 over the catalysts. According to the experimental data, the correlative kinetics parameters were determined based on Eley-Rideal mechanism model. The in- trinsic kinetic equation was obtained. The activation energy of the reaction was 41,9 kJ/mol.
