Preparation of ZnF2 Nano-Particles by Electrochemical Anodization Method

Article Preview

Abstract:

ZnF2 nano-particles were prepared by electrochemical anodization method at room temperature. Zn foil acted as anode and Pb sheet served as cathode, and the complex solution of NH4F-H2O2-C2H5OH was used as electrolyte. The morphology, composition and crystalline structure of the as-prepared product were characterized by SEM, EDS and XRD techniques. The results showed that the product was rhombic nano-particles with the length of 50-200nm and the width of 50-100nm, the crystalline structure of the product was ZnF2 and ZnO, and the ZnF2 was the dominant component. Effects of NH4F concentration, applied voltage and anodization time on the morphology of the product were investigated.
