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.
