A lithium-mediated electrochemical method for ammonia synthesis, relating to the field of ammonia synthesis technology, solves the technical problems of severe side reactions, limited nitrogen mass transfer, and poor interfacial stability in existing lithium-mediated ammonia synthesis systems. Tetra(4-formylphenyl)porphyrin iron and an amino-containing multifunctional organic ligand are added to a mixed solvent of n-butanol and o-dichlorobenzene. An acid catalyst is added, and after stirring until homogeneous, the mixture is degassed and sealed for reaction. The solid product is collected by centrifugation, washed, and dried to obtain COF powder. This powder is then added to an ethanol-water solution, followed by ultrasonic dispersion with Nafion solution. The powder is then drop-coated / sprayed onto the surface of a carbon paper current collector and dried. This powder is used as the working electrode, with a platinum mesh as the counter electrode, a platinum wire as the quasi-reference electrode, and a LiBF4 tetrahydrofuran solution as the electrolyte. Ethanol is used as the proton donor, and electrolysis is performed under a nitrogen atmosphere using a constant current. This invention can be applied to the field of ammonia synthesis technology.
