Abstract: This paper summarized and analyzed the literature on the preparation，doping mechanism，and application in different fields of heteroatom-doped porous carbon in recent years. Here，we summarized and classified the preparation methods of heteroatom-doped porous carbon，and at the same time，we comprehensively analyzed the mechanism of the doping process. We intended to find a clear common road for preparing heteroatom-doped porous carbon through the above summary and analysis，which facilitated researchers to understand the physical and chemical reaction mechanism of the doping process and the preparation method of doped porous carbon. Finally，we put forward some suggestions on the challenges faced by developing heteroatom-doped porous carbon.

Key words: porous carbon, doped mechanism, heteroatom-doped, adsorption, catalysis, energy-storage
