摘要

通过电喷雾和二步热处理法制备得到无硬团聚的ZnO纳米微粒, 为制备无硬团聚氧化物纳米粉体提供了一种新方法. 试验采用添加适量PVP的Zn(CH3COO)2·2H2O的乙醇溶液作为电喷雾液体, 经过锥形喷雾得到均匀的微米级小液滴. 干燥后的喷雾产物先后在氮气炉和空气炉中分别600℃和400℃保温1h进行二步热处理. SEM、XRD测试结果表明, 使用该方法制备得到的ZnO纳米微粒粒度均匀, 结晶完整, 无硬团聚, 具有六角纤锌矿结构.

Abstract

Agglomerate-free ZnO nanoparticles were prepared by electrospraying and subsequent two-step heat treatment, providing a novel way for the fabrication of agglomeratefree oxide nanopowders. Using Zn(CH3COO)2·2H2O ethanol solution added proper polyvinylpyrrolidone as electrosprayed liquid, a cone-jet was successfully formed that produced symmetrical micron droplets. The electrosprayed products were dried then. Agglomerate-free ZnO nanoparticles were derived after annealing the dried electrosprayed products in nitrogen at 600℃ for 1h followed by annealing in air at 400℃ for 1h. Results of SEM and XRD tests demonstrate that the as-prepared ZnO nanoparticles are well developed with a uniform size, and a hexagonal wurtzite structure.
