Nickel nanoparticles have wide application prospects in the fields of high efficiency catalysts, light absorbing materials, sensors, and other fields. The metal elements doped in the nickel nanoparticles can not only improve the reduction ability of the nickel metal particles in the nickel-based catalyst and reduce the activation temperature of the catalyst, but also the formation of bimetallic active site catalyst can inhibit the carbon deposition of the catalyst. Therefore, nickel-based bimetallic nanoparticles can improve the activity and stability of the catalyst. The main process methods were introduced for preparing nickel-based bimetallic nanoparticles at home and abroad, namely chemical reduction, impregnation, sol-gel, electroless plating, and displacement reaction method. Their advantages and disadvantages were briefly described, and the future development direction was analyzed. It is proposed that the focus of future research is to optimize the structure of nickel-based bimetallic nanoparticles, the interaction between the metal and the carrier, the particle size and dispersion of nickel, to prepare the high activity and stability of nickel-based catalysts.
