Abstract：This review aimed to summarize the research progress of bimetallic catalysts in the hydrogenation of halogenated nitrobenzenes. Initially, the emphasis was placed on noble metal-based bimetallic catalysts, with detailed discussions on the performance of Pt-based and Pd-based bimetallic catalysts in the hydrogenation of halogenated nitrobenzenes. Additionally, other noble metal-based bimetallic catalysts were introduced. Subsequently, non-noble metal-based bimetallic catalysts, comprising Cu, Fe, Co, Ni, and their combinations, were explored. Bimetallic catalysts could combine the properties of two metals to form synergistic effects, significantly improving the catalytic activity, selectivity, and stability of halogenated nitrobenzene hydrogenation, while enhancing poisoning resistance. This provided new ideas for the efficient application of noble and non-noble metal-based bimetallic catalysts under complex reaction conditions. This review offered theoretical foundations and references for further research and applications of bimetallic catalysts in the hydrogenation of halogenated nitrobenzenes, emphasizing the importance of bimetallic catalysts in the field of catalysis and pointing out directions for future research and applications.
