用浸制法制备,ZnO/Fe2O3为光催化剂,日光灯为灯源,以苯酚降解为探针反应,考察了不同ZnO负载量对ZnO/Fe2O3为光催化剂的活性的影响,并考察不同光源,催化剂用量,苯酚的初始浓度,溶液的PH值和降解温度对苯酚光催化降解过程的影响.结果表明,ZnO负载量的最佳量为3%,最佳的工艺条件是苯酚浓度是20mg/L,催化剂用量为0.05g,PH值为13时在常温下用日光灯光照射,能较好地降解苯酚.

Soakage preparation, ZnO/Fe2O3 as photo catalyst,daylight lamp as light source,phenol degradation as probe reactivity,test affect of different load of ZnO versus ZnO/Fe2O3 as photo catalyst active.And also test affect of different light source,catalyst amount consumed,initial concentration of phenol.The conclusion is that the firstrank load of ZnO is 3%,first-rank arts and crafts condition is initial concentration of phenol as 20 mg/L, the load of catalyst is 0.05g, PH value as 13 and at the point of normal temperature the ZnO/Fe2O3 under irradiation of daylight lamp can degrade more phenol.
