Electrochemical Synthesis of Porous Copper(II) Oxide Microparticles with Rectangular Hexagonal Morphology

摘要

Microparticles of CuO were obtained by thermal decomposition of copper(II) oxalate synthesized by pulse electrolysis of an oxalic acid solution with a sacrificial copper anode. Scanning electron microscopy showed that the particles are rectangular hexagon-shaped with a size of 0.2-5 mu m and form complex irregular aggregates with a porous structure. The use of the water-dimethylformamide solvents with a volume ratio 1 : 1 is optimal to achieve the desired morphology of the product.
