摘　　要：考察了制备方法、活性组分负载量和焙烧温度对Cu/A l2O3选择性催化还原NO的影响。结果表明,采用溶胶-凝胶+浸渍法制备的Cu/A l2O3催化剂活性最好;负载Cu质量分数为15%时,催化剂的活性温域最宽,最大活性温度最低,催化活性最好;最佳焙烧温度为750℃。Influence of preparation condition, i. e. , preparation method, copper content, calcination temperature, on selective catalytic reduction of NO over Cu/Al2O3 were investigated. The results showed that sol-gel ＋ impregnation method was the most appropriate preparation method ; optimum activity, broadest activity window and lowest activation temperature were attained at copper loading 15% （mass fraction） ; the optimum calcination temperature was 750 ℃.
