摘要
高效催化臭氧化催化剂的研制是金属催化臭氧化技术发展的重点.采用浸渍法,以Al2O3为载体,制备了铜的负载型金属催化臭氧化催化剂.以松花江水的UV254去除率作为催化剂活性指标,通过正交试验,确定催化剂的最佳制备工艺.使用扫描电镜和比表面测定仪对催化剂结构进行了表征.实验结果表明:当浸渍液浓度为1 mol/L,浸渍时间为6 h,焙烧温度为300℃时,所制得的铜催化剂具有很高的催化活性.
Efficient heterogeneous catalytic ozonation is a promising advanced oxidation technology for water treatment. Al2O3 supported copper catalysts （Cu/Al2O3 ）were prepared by immersion method, and the structures were characterized by BET and SEM techniques. The preparations methods and conditions on catalytic activities have been studied and the best reaction conditions have been obtained. The results show that the catalysts of Cu/Al2O3 will have very high catalytic activities, when the concentration of absorption is 1 mol/L, the hours of absorption is 6 h and the temperature of bake is 300℃.
