摘　　要：中空纳米纤维因其比表面积大、密度小等特性近年来备受关注。通过静电纺丝制得聚乙烯醇(PVA)纳米纤维,并采用水热合成法在经热处理的PVA纳米纤维表面包覆一层锌铝氢氧化物,再经高温煅烧处理成功制得掺杂铝元素的氧化锌(AZO)中空纳米纤维。通过扫描电镜、热重分析仪进行测试表征,结果表明所得产物具有明显的中空结构,并对甲基橙有光催化降解性能。The hollow nanofibers have raised many concerns due to their special characteristics. The PVA nanofibers were prepared by electrospinning. After heat-treatment,PVA fibers were coated with zinc aluminum hydroxide via hydro- thermal synthesis. Finally, hollow AZO nanofibres were produced after calcination. The resultant fibers which showed obvi- ous hollow structure were characterized by SEM and TGA. Moreover,hollow AZO nanofihers revealed good photoeatalytie degradation of methyl orange.
