Abstract The anodic behaviour of zinc was investigated in ethanol solution containing LiCl and water. Zinc was polarised by using cyclic voltammetry and chronoamperometry techniques. During the course of the dissolution of zinc, a colloidal suspension of ZnO nanoparticles was obtained in 0.1 M LiCl/ethanol solutions that contain H 2 O. The suspension is formed only if water is present, and the rate of the process depends on the water content. Moreover, the concentration of H 2 O directly influences the size of the particles. However, there is evidence of a Zn 5 (OH) 8 Cl 2 · H 2 O admixture, which is detectable in the precipitates obtained with a high concentration of water. Polarisation of zinc under the given conditions is a very simple method of producing ZnO nanoparticles. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
