This paper dealt with the preparing conditions and morphology of tetrapod-like zinc oxide (T-ZnO) whiskers with an angle of 109 degrees 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 EDS and XRD patterns of T-ZnO whisker, in which the peaks are sharp with narrow half-widths and can be identified as a wurtzite ZnO structure. Morphology of T-ZnO whiskers was affected greatly by white carbon black as mold catalyst and supersaturations ratio(the fractional pressures of zinc vapor vs pressed air).
