| 摘 要： | 以聚苯乙烯微球为模板、六水硝酸亚铈为铈源、六亚甲基四胺为沉淀剂,制备不同壳厚的氧化铈空心微球;利用XRD、TEM、FESEM、XPS和氮气吸附一脱附等手段,对所制备样品的微观结构进行表征.将所制备的Ce02空心微球用于甲基橙模拟染料废水的脱色处理.结果表明:CeO2空心微球具有多孔结构,表面平均孔径约为10 nm,球径约为200～250 nm,壳厚约为10～30 nm,壳层是由粒径为5～10 nm的CeO2颗粒所组成;甲基橙溶液经CeO2空心微球处理60 min后,其脱色率可达95%以上,表现出良好的脱色性能.

| Abstract: | The porous ceria hollow microspheres with controlled shell thickness were synthesized by a simple polystyrene sphere template method using cerium nitrate as cerium resource,hexamethylenetetramine as precipitating agent.The microstructure and properties of the as-synthesized samples were characterized by XRD,TEM,FESEM,XPS and N2 adsorption-desorption.The decolorizing performance of the ceria hollow microspheres on methyl orange dye waster water was also investigated.The results indicate that the ceria hollow... |
