▎ 摘　　要

NOVELTY - Preparing ozone-enhanced graphite nitrogen-doped graphene catalytic material comprises (i) after generating oxide, introducing graphene and water, where the graphene oxide ratio is 75-85 wt.%, carrying out hydrothermal reaction for 0.5-4 hours at 40-150℃ to obtain oxide etching; and (ii) mixing graphene dispersion after oxide etching with nitrogen precursor, where the nitrogen precursor content is 2-10 wt.%, and heating at a low temperature of 40-200℃ under the protection of a carrier gas, reacting for 1-8 hours under annealing conditions to obtain an ozone-enhanced graphite nitrogen-doped graphene catalytic material. USE - The method is useful for preparing ozone-enhanced graphite nitrogen-doped graphene catalytic material. ADVANTAGE - The method: uses oxide etching pre-treatment, hydrothermal synthesis and synergistic effect of low temperature annealing by adjusting the oxide etching time under the proper reaction condition, reaction temperature, lifting high conductivity, high catalytic activity and stability of graphite nitrogen content, improve the catalytic activity of the hybrid material after graphene; can improve the selectivity of catalytic material directional control, which is good for improving catalytic material performance from micro-structure as cutting point, and has important meaning in deepening theoretical research and hybrid graphene material in market popularization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for ozone-enhanced graphite nitrogen-doped graphene catalytic material, is prepared by the above method.
