Metal-nitrogen-carbon (M-Nx-C), possessing prominent advantages of high reactivity, high selectivity, facile synthesis, have presented potential to replace the conventional platinum-based catalysts. However, when these catalysts are used in the oxygen reduction process of fuel cells, the low active site density and insufficient durability restrict application. It is found that modulating the electronic structure and spatial configuration of the active site by doping with various metal/ nonmetal elements can significantly enhance the oxygen reduction activity and stability of M-Nx-C catalysts, which has become a popular research topic in the field. This article reviews the main research works in recent years at home and abroad on the doping of various metal/ nonmetal elements to enhance the performance of M-Nx-C carbon-based catalysts, including the studies on doping of metal elements and doping of nonmetal elements. The article also summarizes and points out the problems and challenges faced by M-Nx-C carbon-based catalysts, and gives an outlook on their development prospects and future research directions.
