【Abstract】 Nickel complexes were directly prepared by electrochemical dissolution of nickel in non-aqueous media. The products were characterized by FT-IR spectrum and Raman spectrum. The influence of temperature and conductive additives on product yield was also investigated. The experiments at the temperature under 30～40 ℃ with R 4NBr as a conductive additive gave improve yields. The study showed that the direct electrochemical preparation of nickel complexes had high current efficiency and electrolysis yield. These nickel complexes had high purity and could be directly used as precursor of nanometer oxides.更多还原
