Investigation on Electro reduction Behaviour of Copper Anodic Products in Concentrated NaOH Solutions Ⅱ. Electro reduction of Cu(Ⅱ) Products
- 1997年第3卷 
采用恒电势氧化－动电势或恒电流还原法研究了铜在浓碱溶液中二次氧化产物的阴极还原行为，共分辨出７个阴极电流峰或相应的多个阴极电势平阶．对各阴极峰的归属进行了指认，并探讨了铜阳极二次氧化反应历程Potentiostatic oxidation potentiodynamic or galvanostatic reduction methods have been used to study the cathodic reduction behaviour of various products anodically formed on the second stage of copper oxidation in concentrated NaOH solutions. Seven cathodic current peaks and the corresponding cathodic potential plateaus are observed on the potentiodynamic E/i curves and the galvanostatic E/t curves, respectively. In the negative potential scan, there are three couples of voltammetric peaks which have been attributed to the formation and reduction of CuO, Cu(OH) 2 and Cu(Ⅱ) ion, respectively. The complicated mechanism for the electro formation of the three Cu(Ⅱ) species are discussed.
