Abstract

None:

Electrochemical nitrite reduction is a potential way to achieve ammonia electrosynthesis, nitrite-containing sewage disposal, and energy supply simultaneously. Herein, a novel Cu-CoSe₂ electrocatalyst was synthesized for nitrite reduction, which achieves an impressive NH₃ yield of 4.79 mmol h^-1 cm^-2, and a high NH₃ faradaic efficiency of 98.7% at -0.3 V vs. RHE in alkaline solution.

Preparation of Amines: Reduction of Oximes and Nitro Compounds

Oximes can be reduced to primary amines using catalytic hydrogenation, hydride reduction, or sodium metal reduction. The reduction of aliphatic and aromatic nitro compounds to primary amines takes place by either catalytic hydrogenation or by using active metals like Fe, Zn, and Sn in the presence of an acid.
Though catalytic hydrogenation can reduce nitrobenzenes, the reduction is nonselective in the presence of other functional groups. For instance, if nitrobenzene contains an aldehyde group,...
