Electrosynthesis and Characterization of Copper Oxalate Nanoparticles

Abstract

Electrosynthesis has been proposed to preparation of copper oxalate nanoparticles in different sizes by electrolysis of copper plate as anode in sodium oxalate solution. The results showed that particle size of product could be tuned by reaction parameters such as electrolysis voltage and oxalate concentration. Detailed particle size of compound as a function of electrolysis voltage shows that increasing voltage from 8 to 20 V decreases particle size of CuC₂O₄. Also, particle size of produced copper oxalate at a constant voltage depended on concentration of oxalate solution. Under optimum condition the average particle size of product is about 22 nm.
