Purpose: The aim of this paper was to investigate an effect of the applied electrolyte on a composition and morphology of synthesised particles, which consist of copper compounds. Design/methodology/approach: We present electrochemical investigations of copper in organic solutions of LiClO4 and LiCl, which are unhydrous or contained 3% of water. The SEM with EDX investigations determined morphology and composition as well as estimated a size of the obtained copper-salts or copper oxide particles. Findings: A type of anion and an addition of a very small quantity of water have a substantial influence on a composition and morphology of the anodic dissolution products. In unhydrous solution and in solution containing LiClO4 copper-salts were obtained. In alcohol solution of LiCl containing 3% of water copper oxide particles were obtained. Research limitations/implications: In some cases the chemical composition of the produced nanoparticles could not have been determined because of fast decomposition of the product. In the future, it is plannned to analyse an effect of the potential on a synthesis. Practical implications: Synthesis of various nanoparticles is presented in the paper, what may have practical applications. Originality/value: The paper proposes a new electrochemical method, which leads to a synthesis of copper oxide particles.
