2-nitroaniline (2-NA) is highly toxic and environmental contaminant. It is reduced to less toxic and environmental benign product o-phenylenediamine by using different reducing agents like sodium borohydride, potassium borohydride, or hydrazine hydrate in the presence of various catalytic systems. These catalytic systems have various advantages and drawbacks. Silica-supported gold nanoparticles are frequently reported catalyst for the reduction of 2-nitroaniline in aqueous medium. In this review article, different catalytic systems reported for reduction of o-nitroaniline under various reaction conditions have been discussed. The critical review of the recent research progress for development of novel catalysts used for the reduction of 2-nitroaniline has been provided here.
2-硝基苯胺（2-NA）是一种剧毒且对环境有污染的物质。在不同的催化体系中，使用不同的还原剂，如硼氢化钠、硼氢化钾或水合肼，可以将其还原为毒性较小且环境友好的邻苯二胺。这些催化体系各有优缺点。负载型金纳米粒子是一种常用于在水相介质中还原 2-硝基苯胺的催化剂。本文综述了不同催化体系在不同反应条件下还原邻硝基苯胺的报道，并对新型催化剂在还原 2-硝基苯胺方面的研究进展进行了评述。
