Method for catalytic preparation of furfural from biomass using phenolic hydroxyl-functionalized covalent organic framework materials

Abstract

A method for catalytic preparation of furfural from biomass using phenolic hydroxyl-functionalized covalent organic framework materials is provided. The present invention uses monomers containing phenolic hydroxyl groups, synthesizing imine-functionalized covalent organic framework materials (COFs) through Schiff base reactions and dehydration condensation. The constructed phenolic hydroxyl-functionalized COFs have a large specific surface area, rich pore structure, high crystallinity, strong thermal stability, and numerous acidic sites, enabling efficient catalysis of biomass raw materials to produce furfural. Innovatively, the present invention applies phenolic hydroxyl-functionalized COFs in the catalytic reaction for preparing furfural from biomass, opening a new sustainable path for the high-value utilization of renewable biomass resources to produce furfural chemicals. It allows for the high-selectivity production of furfural from biomass under mild conditions, with high stability, addressing issues such as poor selectivity and difficulty in reusing catalysts in the production process of furfural.
