摘　　要：以锌粉为原料,高岭土为模板型催化剂,研究了锌在高温气相氧化反应条件下的成核、生长最终生长成为四脚状氧化锌晶须(T -ZnOW )的生长习性。通过扫描电镜对晶体形态进行研究,经分析表明模板催化剂的结构及用量对T -ZnOW形态有着影响的显著,并利用其生长习性的特点,制备了大小分布均一且形态规整的T -ZnOW。The growth characteristics of Tetra pod like Zinc Oxide whisk ers were studied, which were prepared by vapor-phase oxidation of zinc metal in the air by int roducing kaolin as a reaction catalyst instead of white carbon black used before . Through the SEM, the morphology of Tetra pod like Zinc Oxide whiske rs was studied, and the results showed that the microstructure and proportion of modeling catalyst had a great affect on the morphology of Tetra pod like Zinc Oxide whiskers. Thro ugh controlling the above conditions, the regular Tetra pod like Zin c Oxide whisker was prepared with high yield.
