Ligand-modified bimetallic metal-organic framework anode electrocatalyst, the preparation method thereof and the use thereof

Abstract

A method for preparing a ligand-modified bimetallic metal-organic framework anode electrocatalyst, comprising steps of: dissolving a nickel source and a cobalt source in a dimethylformamide (DMF) solvent; dissolving 1,4-benzenedicarboxylic acid and 1,1'-ferrocene dicarboxylic acid in a DMF solvent, and adding deprotonating agent solution; placing the solutions into a reactor for hydrothermal synthesis; after the hydrothermal reaction, allowing the solution to cool to room temperature and then centrifuging for washing to obtain a powder; placing the powder on a nickel foam substrate and drying it in a vacuum oven to obtain the ligand-modified bimetallic MOF anode electrocatalyst. The molar ratio of the nickel source to the cobalt source is
