▎ 摘　　要

NOVELTY - Preparation of nitrogen-doped porous graphene involves providing an amino-modified graphene oxide referring to formation of electrostatic adsorption effect between an amino group and an oxygen-containing functional group on the surface of graphene oxide to bind the amino group to the surface of graphene oxide, dispersing the amino-modified graphene oxide in water to form a dispersion, controlling the solid content of the dispersion to 50-200 mg/mL to prepare a thick slurry containing amino-modified graphene oxide, and irradiating the slurry with microwaves under a protective gas atmosphere. USE - Preparation of nitrogen-doped porous graphene used as catalyst or used for preparing catalyst (all claimed). ADVANTAGE - The method is simple and convenient, ensures simultaneous nitrogen doping during the pore forming process, thus improving the electrocatalytic activity of porous graphene, and provides nitrogen-doped porous graphene having uniform pore size and distribution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for nitrogen-doped porous graphene.
