[특허 요약] A method for preparing a transition metal electrochemical catalyst according to an embodiment of the present disclosure includes dissolving a nitrogen precursor and a transition metal precursor in a polyol-based solvent so as to prepare a solution in which transition metal ions and free anions are coordinated, and mixing same with a support so as to prepare a mixture, igniting the mixture so as to carbonize the polyol-based solvent, thereby forming transition metal nanoparticles encompassed by carbon, performing heat treatment in order to carbonize remaining organic matter contained in the mixture, and removing, through acid treatment, impurities and transition metal nanoparticles not encompassed by carbon, and then removing remaining acid through washing and additional heat treatment, thereby a nanocatalyst having a structure in which a single-atom transition metal-nitrogen bonding structure and/or transition metal nanoparticles encompassed by carbon exist is synthesized.
