Fuel cells have the great prospect in energy storage technology from the perspective of energy conservation and ecological protection. However, oxygen reduction reaction (ORR) always proceeds sluggishly leads to limited performance. Choosing an excellent ORR electrocatalyst is considered to be an effective strategy. Herein, we have presented an easy synthesis method to prepare highly nitrogen-doped porous carbon nanosheets (HNPC) electrocatalysts. The as-synthesized HNPC electrocatalysts delivered excellent catalytic properties by 4e– transfer pathway with extremely few HO2–, due to excellent compositional characteristics (highly N doping) and structural features (porosity). It provides some guidance for the synthesis of excellent electrocatalysts, which will have certain significance for the development of fuel cells.
