An efficient furfural oxidation active electrocatalyst based on electron beam irradiation and a preparation method and application thereof

Abstract

This invention relates to a highly efficient active electrocatalyst for furfural oxidation based on electron beam irradiation, its preparation method, and its application. The preparation method includes the following steps: dissolving an aminobenzene precursor and a fluorine-containing precursor in a first organic solvent, performing a hydrothermal reaction, filtering, and dialyzing to obtain a carbon quantum dot stock solution; dissolving the carbon quantum dot stock solution and a carboxylic acid in a second organic solvent to obtain a carbon quantum dot-ligand solution; adding an inorganic salt solution of nickel and iron to the carbon quantum dot-ligand solution, mixing thoroughly, adding triethylamine, irradiating with an electron beam, centrifuging, washing, and vacuum drying to obtain a fluorine-nitrogen-doped carbon quantum dot-NiFe-MOF nanosheet composite material. Compared with existing technologies, the carbon quantum dots in this invention have a dual function as structure regulators and active sites, and electron beam irradiation can produce a radiation etching effect on the product, leading to defects inside the material, thus giving the synthesized fluorine-nitrogen-doped carbon quantum dot-NiFe-MOF nanosheets highly efficient electrocatalytic furfural oxidation activity.
