dc.description.abstract本文采用共沉积法制备了以铜为基体的不同Cu/Ni比的Cu-Ni合金镀层,并用稳态极化法研究了这些镀层在使用硝基苯(NB)和1,5-二硝基蒽醌(1.5-DNA)制备对氨基苯酚(PAP)及1,5-二氨基-4,8-二羟基蒽醌(1,5-DA-4,8-DHA)等电化学还原过程中的阴极活性.研究表明,在PAP和1,5-DA-4,8-DHA电合成体系中,不同Cu/Ni比的合金阴极具有不同的交换电流密度(io)和表观活化能(EA),其中以0.05mol/LCuSO4·5H2O+0.6mol/LNiSO4·6H2O+0.25mol/LNa3Cit·2H2O组成的镀液,并在控制电流密度为0.6A·dm-2、pH值为6、体系温度为50℃等工艺条件下镀制的Cu-Ni合金试片(CN-30),具有最大的io和最小的EA值,与常规所用的Cu、Cu/Hg、蒙乃尔合金等阴极相比,CN-30试片的电极性能最佳zh_CN
dc.description.abstractCuNi alloy on the basis of copper at different ratio Cu/Ni are prepared by codepostion. The cathode activtiy of film are studied by steadystate polarization for electroreduction nitrobenzene (NB) and 1,5dinitroanthraquinone (1,5DNA) to paminophenol and 1,5diamino4,8dihydroanthraquinone respectly. The results show that the alloy cathodes at different ratio Cu/Ni have different exchange current density (io) and apparent activition energy (EA). The alloy (CN30) has maximal io  and minimal EA by codeposition at the following conditions: electrolyte: 0.05 mol/L CuSO4·5H2O+0.6 mol/L NiSO4·6H2O+0.25 mol/L Na3Cit·2H2O; current density: 0.6 A/dm2 , pH=6, temperature at 50 ℃. Compared with the common cathodes such as Cu, Cu/Hg, Monel alloy, CN30 alloy is more suitable in these system.zh_CN
