摘要
采用膨润土作为催化剂,通过高温气相氧化法制备了四脚状氧化锌(T-ZnO)晶须,并研究了实验条件对产物的影响。结果表明:实验温度、催化剂含量和空气流量对T-ZnO晶须的尺寸、规整性、产率等有显著的影响,实验温度为920~980℃,膨润土含量为33%左右以及适当的空气流量条件下,可以得到尺寸均一、结构规整、四脚状含量和晶须产率都较高的T-ZnO晶须。
Tetrapod-shaped zinc oxide(T-ZnO) whiskers were prepared by the method of vapor phase oxidation at high temperatttre with bentonite as catalyst, and the influence of experimental conditions to T-ZnO whiskers were discussed in this article. The results showed that the size, the shape and the product ratio of T-ZnO whiskers were affected evidently by the experimental temperature, the percentage of catalyst and the atmospherical flux. T-ZnO whiskers with uniform size , regular sructure and high yield , perfect ratio were gained when the experimental temperature is 920~ 980℃ ,the percentage of bentonite is about 33% and the proper atmospherical flux.
