The invention discloses a catalyst for catalyzing benzyl compound oxidation to prepare carbonyl compound, a preparation method and application thereof, belonging to the technical field of catalysts. The method adopts a silicon-based mesoporous molecular sieve hard template agent, fills metal oxide into a molecular sieve pore channel, and then removes the hard template agent at a lower temperature to obtain the metal oxide with high specific surface area. Compared with the metal oxide prepared by a coprecipitation method, a sol-gel method and the like, the specific surface area of the metal oxide prepared by the method is obviously improved. The prepared metal oxide with high specific surface area can be used for liquid-phase oxidation reaction of benzyl compounds at low temperature. The method has the advantages of low cost, high conversion rate of the benzyl compound, high selectivity of the corresponding carbonyl compound, mild reaction conditions, good stability and easy separation of the catalyst. |
