The reduction of nitrobenzene by an electrolytic method is fairly simple and it does not require the complicated equipment needed in the vapour phase reduction method. John Wiley Interscience (1947). Nitrogen doped carbon is a kind of favorable cathode material for electrochemical reduction, but deep understanding for the effect of nitrogen concentration and reduction pathway is still needed. P.

The electrochemical reduction performance of NPCs was evaluated by reducing nitrobenzene (NB), and the effects of nitrogen concentration were discussed. The electrolytic reduction of nitrobenzene in strongly acidic medium produces phenylhydroxylamine which rearranges to p-Aminophenol. In this paper, nitrogen doped porous carbon (NPC) with different nitrogen concentration were fabricated by directly carbonization of ZIF-8 under various temperatures. High N concentration facilitates electrochemical hydrogenation reduction reaction. Chem. As shown in Fig. K. Elbs and L. Silbermann,Z. O. W. Brown and J. C. Warner,Trans. Further H* quenching experiment indicates the NPC electrochemical reduction process mainly following an indirect hydrogenation reduction pathway. • volume 2, pages169–173(1972)Cite this article.

Cloudflare Ray ID: 5f7990537f6025d5 Under weakly acidic conditions nitrobenzene on electrolytic reduction gives aniline but under strongly acidic conditions gives p-aminophenol. Phys. Pol. NPC with 22.7% nitrogen concentration exhibited the best NB reduction performance with the NB removal constant about 1.0 h−1 under optimal conditions; the NB removal rate and aniline (AN) production on this NPC are 4.2 and 8.5 times higher than graphite electrode.
