制备了两种含铁柱撑膨润土(Fe-Al-Bent和Fe-Bent),用XRD、BET、TEM对它们进行了性能表征.以偶氮染料OrangeⅡ为目标降解物,考察了它们作为复相Fenton催化剂的光催化性能,以及溶液的pH、H2O2浓度、催化剂用量对OrangeⅡ降解的影响,并与相应的均相Fenton反应进行了比较.结果表明Fe-Al-Bent和Fe-Bent具有很高的比表面积(分别为194.2和114.6m2/g),用Fe-Al-Bent或Fe-Bent作光催化剂的复相光助Fenton反应的催化性能明显优于相应的均相光助Fenton反应.此外复合铁铝柱撑膨润土(Fe-Al-Bent)比单一的铁柱撑膨润土(Fe-Bent)在反应过程中具有更低的铁离子溶出量,它们还具有分离简单、重复使用性好等特点.
