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。 Using bentonite as a catalyst, tetrapod-shaped zinc oxide (T-ZnO) whiskers were prepared by high temperature gas phase oxidation and the effects of experimental conditions on the product were studied. The results show that the experimental temperature, catalyst content and air flow have significant effects on the size, regularity and yield of T-ZnO whiskers. The experimental temperature is 920-980 ℃, the bentonite content is about 33% and the appropriate air flow T-ZnO whiskers with uniform size, regular structure, tetrapod-like content and whisker yield can be obtained.
