The invention relates to a bimetallic nanoparticle for electrolyzing water and a preparation method thereof, and belongs to the field of electro-catalysis nano materials. According to the technical key points, the method comprises the following steps: 1) adding a FeCo bimetallic organic framework compound and dopamine hydrochloride into an alkaline solution, stirring for 24 hours, and carrying out solid-liquid separation to obtain MOF/PDA nano cubes, the alkaline solution being a tris (hydroxymethyl) aminomethane (Tris) buffer solution with the pH value of 8.0; 2) carrying out annealing treatment on the MOF/PDA nano cube prepared in the step 1) in ammonia gas atmosphere at different temperatures; and 3) further performing high-temperature carbonization on the solid sample obtained in the step 2) in a nitrogen atmosphere so as to obtain the product The FeCo bimetallic nanoparticle for electrolyzing water has the characteristics of large specific surface area, high conductivity, good stability, good catalytic a
