摘要/Abstract

摘要： 以乙二醇为溶剂，聚乙二醇-10000为表面活性剂，硝酸锌和醋酸钠为原料，利用溶剂热法，合成了氧化锌空心微球。并用X射线衍射、扫描电子显微镜、热重、比表面和孔径分布等对其进行了表征。考察了硝酸锌用量、聚乙二醇-10000用量、反应时间和反应温度等对氧化锌空心微球形貌和大小的影响。考察了氧化锌空心微球催化分解高氯酸铵的性能，结果表明，由于氧化锌空心微球的加入，高氯酸铵的分解温度由442 ℃降低至280 ℃左右。

Abstract: ZnO hollow microspheres were synthesized by a facile solvothermal treatment of zinc nitrate and NaAc in the presence of polyethylene glycol 10000. The products were characterized by XRD, SEM, TG-DSC, BET techniques. The effects of the amount of zinc nitrate, the amount of PEG-10000, the reaction time and the reaction temperature on the morphology and size of products were investigated. The catalytic role of ZnO hollow microspheres in ammonium perchlorate decomposition was investigated. The result shows that ammonium perchlorate decomposition temperature decreases from 442 ℃ to 280 ℃ with the addition of ZnO hollow microspheres.

Key words: zinc oxide hollow microspheres, synthesis, catalysis, ammonium perchlorate
