| titleOfInvention | Nitrogen-doped carbon-coated catalyst, and preparation method and application thereof |
| abstract | A nitrogen-doped carbon-coated catalyst, a preparation method and application thereof. The invention provides a nitrogen-doped carbon-coated catalyst for preparing halogenated aromatic amine by catalytic hydrogenation of halogenated nitroaromatic, which comprises a supported metal catalyst and a coating layer, wherein the supported metal catalyst comprises a carrier and a metal active component, the coating layer is a nitrogen-doped carbon layer, and the thickness of the nitrogen-doped carbon layer is 0.1-10 nm. The metal active component is G-M, G is one or more of noble metals of Pt, Pd, Rh or Ru, and M comprises at least one of Fe, Co, Ni, Sn and Mo metals. The catalyst provided by the invention is applied to the preparation of halogenated arylamine by catalytic hydrogenation of halogenated nitroaromatic, the conversion rate of halogenated nitrobenzene is up to 100%, the nitrogen-doped carbon-coated catalyst has high activity and excellent stability, high-purity halogenated aniline can be obtained, the selectivity can be up to more than 99.7%, the dehalogenation is less than 0.3%, and the dehalogenation is effectively inhibited; and a dechlorination inhibitor does not need to be added into the reaction system, so that the cost is reduced, the complexity of the reaction system is reduced, and the side reactions possibly introduced are reduced. |
