▎ 摘　　要

NOVELTY - Preparing selective oxidation catalyst, involves (a) using water solution containing nitrogen element to dip the carbon-containing material, drying in the inert gas for the first roasting to obtain nitrogen-doped carbon carrier; (b) mixing the nitrogen-doped carbon carrier with the active metal component compound solution to obtain a first mixture; (c) performing the first drying and the first reduction to the first mixture. USE - Method for preparing selective oxidation catalyst. ADVANTAGE - The method is cost-effective. The selective oxidation catalyst is capable of high selectively catalyzing to obtain 2, 5-dimethyl acyl furan. The reaction solvent used is cheap and easy to obtain, avoids using organic oxidant such as nitrate, simplifies the post-processing step of the product, avoids the acid-containing waste water discharge problem, reduces energy consumption, green and environment-friendly. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a selective oxidation catalyst, which is prepared by the method for preparing the selective oxidation catalyst, where the nitrogen-doped carbon carrier has a characteristic peak between the 399-400.5ev N1s of spectral peak XPS analysis of the nitrogen-doped carbon carrier; 2. a preparation method of 2, 5-dimethyl acyl furan, which involves (a) dissolving the 5-hydroxymethyl furfural in the organic solvent to obtain the mixed solution; (b) adding selective oxidation catalyst in the mixed solution, carrying out oxidation reaction.
