Catalytic hydrogenation is an environmentally friendly method for preparing halogenated anilines. So far, the catalysts used for the hydrogenation of nitrobenzene are mainly noble Pt, Pd, Ru based catalysts, and some other non-noble Ni, Co and Fe based catalysts . In the case of hydrogen as the hydrogen donor, some precious metals are often used for direct hydrogenation of nitroaromatics under high temperature and high pressure . According to the catalyst formulation, some metal-based catalysts, especially Pd , showed good catalytic performance, but the current trend in the pharmaceutical and food industries is the progress of economical, green, and environmentally friendly processes. It is very important and desirable to develop more cost-effective and practical application methods. In order to improve the activity and recyclability of the catalyst, researchers immobilize nano-scale catalytically active metal Pd on various supports . These heterogeneous catalysts showed good robustness and separability and had been used in industrial production, including fine chemical production.
