▎ 摘　　要

NOVELTY - A carbon gel catalyst comprises carbon material having whole solid block of any shape, and fixed bed catalyst. The carbon material is a graphite oxide, porous graphene oxide, carboxylated carbon tube and/or its modified product. USE - Carbon gel catalyst used in complex organic reaction catalysis field (claimed). ADVANTAGE - The catalyst exhibits fast and efficient catalytic effects, has simple process, and has high yield and high selectivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the catalyst which comprises putting 5-300 mg/mL carbon material solution to a reactor, putting in freezing dryer, and spray drying.
