▎ 摘　　要

NOVELTY - The method involves dissolving graphite oxide in deionized water to make a graphene oxide solution, and adding glucose powder directly to the graphene oxide solution. The mixed solutions are placed in a reaction kettle, and react at 160-190 °C for 12-24 hours. The cylindrical solid sample is separated, washed, and dried to obtain a precursor after the reaction is completed and cooled. The precursor was placed in an inert atmosphere and raised to 800 °C at a heating rate of 3-5 °C/min, and calcined for 3-6 hours to obtain a nitrogen-doped core-shell structured activated carbon supercapacitor electrode material. USE - Method for preparing high-temperature carbonized nitrogen-doped core-shell activated carbon composite electrode, where heteroatom doping has a wide range of applications in supercapacitors, lithium-ion batteries, zinc-ion batteries, photocatalysis, photoelectrocatalysis and other fields. ADVANTAGE - The method is simple and easy, without adjusting the pH, and biomass glucose raw material easy to obtain, easy for industrial implementation. The nitrogen-doped core-shell structure active carbon super capacitor electrode material prepared by the method has excellent capacitance performance, and has good application prospect.
