Abstract：This review presents the researches of nonmetallic and metal doped or loaded carbon electrode materials in the fields of water decomposition, H2O2 synthesis, fuel cell, and metal-air cell, all of which were very hot topics in 2019. These researches mainly concentrate on preparation method, principle of designing and related catalytic reaction mechanisms of nonmetallic or metal doped/loaded carbon materials, such as single atomic metal (M)-N-C materials. High temperature pyrolysis of organic precursors with doping elements is becoming an important method for preparation of related materials.
