| 摘 要： | 采用电化学原位红外光谱技术研究了对硝基苯酚在铜电极表面及硫酸介质中的电化学反应机理. 对硝基苯酚首先经电还原反应生成对亚硝基苯酚和对羟胺苯酚, 对亚硝基苯酚可发生缔合生成反式二聚体, 最后在较低的电位下, 对羟胺苯酚经电还原生成了对氨基苯酚.

| Abstract: | The electrochemical reduction of p-nitrophenol in sulfuric acid on copper electrode was investigated by in situ FTIR technique. Electroreduction of p-nitrophenol in sulfuric acid led to the formation of p-nitrosophenol first, which could be converted to trans-dimer of p-nitrosophenol, and then p-hydroxylamino phenol. Finally p-hydroxylamino phenol was reduced to p-aminophenol at low potential. |
