Abstract

The application discloses a kind of biochar catalyst and its preparation method and application in catalyzing 5-hydroxymethylfurfural oxidation preparation 2,5-furan dicarboxylic acid.The preparation method comprises the following steps: after mixing trehalose with zinc chloride and potassium chloride, carbonization is pyrolyzed under inert atmosphere to obtain biochar catalyst.The application utilizes efficient, low-cost, renewable catalyst to efficiently catalyze HMF to selectively generate DFF in the presence of potassium hydrogen peroxymonosulfate composite salt, and has the advantages of low catalyst cost, high product yield, high product selectivity, mild reaction conditions, low production cost, no security risks and environmental friendliness.
