Preparation of Nanocrystalline Cupric Oxide by Electrochemical Dissolution of Copper Metal
Abstract:
The precursor Cu(acac)2 was electrochemically prepared by anodic dissolution of fresh metallic copper in absolute acetylacetone using Bu4N·Br as supporting electrolyte. Nanocrystalline CuO could be obtained by direct hydrolysis of the electrolyte solution via refluxing with some amount of NaOH and water. FTIR, elemental analysis, XRD and TEM have been used to investigate the structure of the precursor and nanocrystalline CuO. The results showed that the cupric oxide obtained is of spherical structure with size distribution ranged in 10 nm to 20 nm. The rational electrode potential in electrolysis appeared to be 1.2~1.8 V(vs.SCE).
