▎ 摘　　要

NOVELTY - Preparation of nitrogen-doped graphene-based porous carbon material comprises mixing graphite oxide, soluble sugar and/or its derivative and water, ultrasonically dispersing, adding N,N'-dicyclohexylcarbodiimide, obtaining mixed solution, fully reacting, adding the reaction solution into a hydrothermal reaction kettle, conducting hydrothermal carbonization reaction, centrifuging, using water to wash the solid product, drying, and obtaining the product. USE - Preparation of nitrogen-doped graphene-based porous carbon material used as catalyst (claimed). ADVANTAGE - The method is simple, has mild conditions, easy to obtain raw materials, and good repeatability, and provides nitrogen-doped graphene-based porous carbon material, which has low cost, light weight, and high activity, thus, reducing nitrobenzene, and is green and environment-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for nitrogen-doped graphene-based porous carbon material.
