Preparation of Nano-Porous Zn and Nanowire-Like ZnO by Anodization and Oxidation

Abstract:

Anodization of Zn foil in a salicylic acid-ethanol-H2O electrolyte and the following annealing of the anodized product have been investigated in this paper. Nano-porous metallic Zn were fabricated by anodization, and the Zn nano-pores formation mechanism on the zinc foil was suggested. The diameter of the Zn nano-pores is around 200 nm. Both the electrolyte concentration and potential have significant effect on the morphology and structure of the pores, and the nano-pores formation rate. Nanowire-like ZnO was produced by annealing the nano-porous metallic Zn obtained by anodization. The lengths of the ZnO nanowires range from 2 to 5 μm, and the diameters are in the range of 40~70 nm.
