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.

The application provides a fattening method for Wuzhishan ant chicken, which comprises the following steps: setting an activity area in an orchard, erecting a grass shed above the activity area, connecting a chicken house with the activity area, sequentially adding a fluorescent LED lamp in the chicken house, and adding the fluorescent LED lamp and a blue LED lamp in the chicken house and the grass shed at the same time to obtain target Wuzhishan ant chicken; and the fluorescent powder of the fluorescent LED lamp is mainly prepared from magnesium carbonate, strontium carbonate, yttrium oxide, silicon oxide and aluminum oxide. The application builds an activity place for the ant chicken in the orchard, sequentially adds the fluorescent LED lamp in the chicken house, and adds the fluorescent LED lamp and the blue LED lamp in the chicken house and the grass shed at the same time, so that the ant chicken is bred, the metabolism level of the ant chicken is reduced, the fat deposition is promoted, the crude fat content of the ant chicken obtained after 100 days of breeding reaches more than 10%, and the purpose of rapidly fattening the ant chicken is achieved.
