摘要/Abstract

摘要： 以单分散性良好的聚苯乙烯（PS）微球为模板，采用化学浴沉淀法制备了PS@ZnO纳米复合材料。利用SEM、TEM、XRD、FTIR和DRS等测试手段对样品的形貌、结构、组成和光学性质进行表征，在紫外光照射下进行亚甲基蓝溶液的光催化降解研究，并考察复合材料的光催化性能。结果表明：该方法制备的PS@ZnO纳米复合材料具有核壳结构，颗粒均匀，呈球形，核的平均粒径约为200nm，壳层厚度约20nm，具有良好的光催化性能，且其催化效率比单纯ZnO提高了13%，而且可以重复使用。

Abstract: Polystyrene@ZnO nanocomposites were synthesized by chemical bath precipitation method with well-dispersed polystrene microspheres as the template. The morphology,structure,composition and optical property of the as-prepared nanocomposites were characterized by the SEM,TEM,XRD,FTIR and DRS. The photocatalytic properties of the as-prepared samples were evaluated by photocatalytic degradation of methylene blue aqueous solution under UV light irradiation. The results showed that the prepared PS@ZnO nanocomposites was of core-shell structure and mono-dispersed. The core of the nanoparticles was typically spherical with an average diameter of ca. 200nm and the shell thickness was ca. 20nm. In addition,the degradation rate of PS@ZnO core-shell nanocomposites was 13% more than that of pure ZnO and they can be reused.

Key words: polystrene microspheres, precipitation method, composites, core-shell structure, photocatalytic, reused
