NOVELTY - The preparation method of nitro compound involves: (A) adding graphene, a nitrification substrate and a nitrogen dioxide agent to a reactor; (B) setting the reaction temperature to 30-160 degrees C, and setting the reaction pressure to normal pressure to 7 MPa; and (C) fully reacting under an oxygen atmosphere. The nitration substrate is aliphatic, alicyclic, aromatic and heterocyclic compounds or their mixtures. USE - The method is useful for preparing nitro compound. ADVANTAGE - The method enables economical preparation of nitro compound with high yield and utilization rate, and reduced energy consumption.
