TLDR
In this article, it was shown that the yield of nitrobenzene and the maximum current density for the reaction is dependent upon the solvent, the cathode metal, the electrode potential, the concentration of acid and the rate of stirring of the catholyte.Abstract:
The electrochemical reduction of nitrobenzene has been studied in aqueous organic solvents containing sulphuric acid. It is shown that the yield ofp-aminophenol and the maximum current density for the reaction is dependent upon the solvent, the cathode metal, the electrode potential, the concentration of acid and the rate of stirring of the catholyte. The changes of products would not be obvious from theI-E curves but it is possible to find conditions where the yield ofp-aminophenol is > 75% at a current density of 150 mA cm−2.read more

Review on selective hydrogenation of nitroarene by catalytic, photocatalytic and electrocatalytic reactions
TL;DR: In this article, the authors summarize the breakthroughs on the development of multiple catalytic technologies in the past decade, including direct hydrogenation using high-pressure hydrogen; transfer hydrogenation with reductive compounds; photocatalytic and electrocatalytic hydrogenation accompanied with water oxidation, and focus on how to understand the two key element steps including hydrogen dissociation and the activation of nitro group in the process of hydrogenation.

TL;DR: In this article, the authors used density functional theory (DFT) with the inclusion of van der Waals interaction to study the reaction mechanism in the nitrobenzene reduction reaction over the Pt(1.1) model catalyst and found that double H-induced dissociation of N-O bond was the preferential path for the activation of nitro group, having a much lower reaction barrier than that of the direct dissociation and single H-induction paths.

TL;DR: In this article, an account is given of new methods for the electrochemical preparation of p-aminophenol by the reduction of nitrobenzene, and it has been found that control of the electrode potential at a specific value using recently developed potentiostats brings about a marked improvement in the efficiency of the preparation.
