摘要: 以溶胶-凝胶法制备介孔TiO2载体,采用分步浸渍法制备了V2O5-WO3/TiO2催化剂,借助BET、NH3-TPD、H2-TPR、SEM、活性评价、In-situ FT-IR等手段,考察了催化剂的结构、酸性、还原性、脱硝活性及反应机理等。介孔TiO2载体比表面积为158.6 m2/g,制成催化剂后比表面积略有降低,约为136.7 m2/g。针对模拟烟气在φNH3/φNO=0.8的条件下测试催化剂的脱硝活性温度窗口为250~400 ℃,脱硝转化率达到80%。NH3-TPD和H2-TPR表征结果表明,催化剂在活性温度范围内具有典型的表面酸性位,载体TiO2与V2O5之间存在的相互作用使得V2O5还原温度降低。利用In-situ FT-IR研究NH3和NO在V2O5-WO3/TiO2催化剂表面吸附和氧化的反应过程发现,NH3可同时吸附在L酸位和B酸位,NH3在活性位上氧化脱氢形成NH2物种是SCR脱硝反应的控制步骤。研究NO+O2+NH3反应时发现,吸附NH3的催化剂引入NO和O2后,共价吸附的NH3首先消失。选择性催化还原反应发生在吸附态NH3和气态或弱吸附态的NO之间,该反应遵从Eley-Rideal反应机理。
