A method for preparing and separating monodisperse amorphous nickel nanoparticles comprises the following steps: taking acetylacetone nickel as a raw material; taking whiteruss as a reaction medium; taking trioctyl phosphine and oleylamine as stabilizing agents (or: protective solutes, surface modifying agents); taking an organic ferric compound as a catalyzer; taking polylol as a morphological modifying agent; mixing the above substances in a kettle-type reactor according to a certain ratio; heating the substances with hydrogen to the reaction temperature (150 to 350 DEG C); reacting for 3 hours; obtaining amorphous nickel nanoparticles; and adopting an external applied magnetic field to assist the solvent fractionating method, so as to separate the nickel nanoparticles from the reaction system. The powdery monodisperse amorphous nickel nanoparticles can once again disperse into organic solvents such as chloroform, sherwood oil, etc. without sedimentation.
