纳米ZnO材料的制备与应用研究进展

纳米ZnO材料较普通ZnO材料，有着许多优异的性能和广泛的应用价值，对它的研究得到了高度的重视，而国内相对国外显得滞后。系统介绍了纳米ZnO粉体和薄膜的制备方法，认为水热法、sol—gel法、喷雾热分解法是纳米ZnO材料降低成本、产业化制备最有潜力的方法。而纳米ZnO材料将不仅可以在传统领域逐步替代普通ZnO材料，并五将在普通ZnO材料无法涉足的新型领域，如光电、敏感领域开拓出新的应用前景。

Progress in Preparation and Application of ZnO Nano-Material

Compared with conventional ZnO materials, ZnO nano-material has many special properties and great potential for wide application. In this paper,the preparation methods of ZnO nano-material in the powder and thin film forms are systematically discussed, and the hydrotherma process, sol-gel process, and spray pyrolysis are thought as the most promising methods. In addition to replacing conventional ZnO materials in conventional areas, ZnO nano-materials will also be used in some new areas, including photoelectronics and sensing elements, which preclude the use of conventional ZnO materials.
