摘要(Abstract)：

采用浸渍法制备了Cu-V/TiO2系列催化剂,考察了催化剂的低温脱硝活性,并通过N2低温吸附-脱附、X射线衍射、红外光谱、热重、NH3程序升温脱附等手段对催化剂进行了表征。结果显示,当Cu/V摩尔比为1:4,反应温度为180℃时,催化剂对NOx的转化率可达90%以上,当烟气中含有0.01%(体积比)SO2时,催化剂Cu1-V4/TiO2的活性能够保持在90%左右。铜离子的加入使得VOx在载体TiO2表面分散更均匀。催化剂Cu1-V4/TiO2具有最高的比表面积,且其表面弱酸量增加,有利于催化活性的提高;抗硫测试后,Cu1-V4/TiO2催化剂表面仅有少量的硫酸铵盐及硫酸铜的形成与沉积,催化剂表现出强抗硫性。
