Copper complexes were directly prepared by electrochemical dissolution of copper in a cell without separating the cathode and anode spaces. The products were characterized by FT-IR and Raman spectra. The influence of temperature and conductive additives on product yield was also investigated. The experiments show that the temperature controlled under 30～40 ℃ and selecting R₄NBr as conductive additivesimprove product yield. The data also show that direct electrochemical preparation of copper complexes have high current efficiency and electrolysis yield. Thesecopper complexes have high purity and can be directly used as precursor of nanometer oxides.

Key words: copper complex, electrosynthesis, nanometer material, sacrificing anode
