采用阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)和阴离子表面活性剂十二烷基苯磺酸钠(SDBS)复配形成的囊泡相自组装合成了微纳结构CeO2-NiO花球,考察了不同Ce/Ni摩尔比对花球微纳结构的影响以及不同微纳结构CeO2-NiO花球的光催化性能.结果表明:在n(Ce)∶ n(Ni)为4至1范围内,均可形成CeO2-NiO微纳结构花球,晶体均保持CeO2萤石结构特征.当n(Ce)∶ n(Ni)=2∶1时,75 nm左右的纳米粒子有序排列组成厚度大约为140 nm花瓣,花瓣有序堆积成9μm左右CeO2-NiO花球.在紫外光照射下,CeO2-NiO微纳结构花球(n(Ce)∶n(Ni)=2∶1)在150 min时间内对活性艳红降解率为95.93%.
