A Study of Preparing and Morphology of Tetrapod-like ZnO Whiskers

Abstract

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).

Key words: Zinc oxide whisker, Tetrapod-like whisker, Preparation, Morphology
