The invention discloses an sp2 hybrid carbon material doped with single dispersed metal atom and a preparation method of the sp2 hybrid carbon material, and relates to an sp2 hybrid carbon material and the preparation method thereof. The invention aims to solve the problems of high preparation cost of metal doped carbon material and uncontrollable metal introduction site. According to the sp2 hybrid carbon material doped with the single dispersed metal atom, a part of metal element is bonded with N atom evenly through a coordinate bond and doped in a sp2 hybrid carbon framework, and the other part is evenly distributed in the sp2 hybrid carbon material doped by the single dispersed metal atom. The preparation method includes steps of firstly, mixing and acquiring a nitrogen source/carbon source fluid mixture; secondly, freeze-drying and acquiring a nitrogen source/carbon source solid mixture; thirdly, sintering to obtain the sp2 hybrid carbon material doped with the single dispersed metal atom. The invention is mainly used for preparing the sp2 hybrid carbon material doped with the single dispersed metal atom.
