摘要: 研究了以锌粉为原料,白碳黑为催化剂,高温气相氧化反应制备任意两针夹角为109°的四脚状氧化锌(T-ZnO)晶须的条件及形态.表面能谱证实产物为纯氧化锌,X射线衍射结果表明,该晶体属六方晶系纤锌矿结构.扫描电镜研究结果表明,模型催化剂白碳黑及气相反应体系的过饱和度对产物四脚状氧化锌晶须的形态影响很大.

Abstract: This paper dealt with the preparing conditions and morphology of tetrapod -like zinc oxide (T-ZnO) whiskers with an angle of 109° between any two legs, which were prepared by vapor-phase oxidation of zinc metal in the air and by introducing white carbon black as a reaction catalyst. The product was pure zinc oxide verified by EDSand XRDpatterns of T-ZnOwhisker, in which the peaks are sharp with narrow half-widths and can be identified as a wurtzite ZnOstructure. Morphology of T-ZnOwhiskers was affected greatly by white carbon black as mold catalyst and supersaturations ratio(the fractional pressures of zinc vapor vs pressed air).
