Mesoporous Phosphorus-Nitrogen Co-doped Carbon Materials for Energy Storage and Conversion: Synthesis and Electrochemical Performance

摘要

Substitutional doping in carbon materials implies that carbon atom in the hexagonal lattice are replacing by heteroatoms, thus resulting in the disruption of the sp2 hybridization of carbon atoms, and in significant changes of the physical/chemical properties. Both theoretical and experimental studies have demonstrated that the intentional incorporation of heteroatoms into the carbon structure could effectively modify its electronic and chemical properties, which can enhance the electric double layer capacitance and electrocatalytic activity of oxygen reduction reaction, and make these materials highly suited for supercapacitor and as nobel-metal-free electrocatalysts for oxygen reduction reaction.
