制备性电解的结果表明，硝基苯在Cu／C－Nafion膜复合电极上的还原产物只有苯胺，可能与电极／Nafion界面的弱酸性环境和其还原中间产物本羟胺在界面的扩散较仅有关．生成苯胺的电流效率随电流密度的增大而减小，随反应液中硝基苯浓度的增大出现一个最大值．这可能是硝基苯的电化学还原过程受某种粒子的扩散控制、峰电流取决于硝基苯在Nafion膜中的溶解度所致．
The results of preparative electrolysis showed that the only products of reduction of nitrobenzene on Cu / C-Nafion membrane electrode were aniline, which may be related to the weak acid environment of electrode / Nafion interface and the diffusion of hydroxylamine at its interface . The current efficiency of aniline formation decreases with the increase of the current density, with a maximum value of nitrobenzene concentration in the reaction solution. This may be due to the fact that the electrochemical reduction of nitrobenzene is controlled by the diffusion of certain species of particles, the peak current being due to the solubility of nitrobenzene in the Nafion membrane.
