摘要： An ammonia production method is a method of producing ammonia from nitrogen molecule using electron supplied from a power supply in the presence of a complex and a proton source. The complex used is, for example, a molybdenum complex (1) that is carried on Merrifield resin. The proton source used is an electrolyte membrane, a solution used in a cathode tank, or both the electrolyte membrane and the solution used in the cathode tank:

摘要： An ammonia production method is a method that produces ammonia from nitrogen molecules by donating electrons from a power supply, protons from a proton source, and the nitrogen molecules from means for supplying a nitrogen gas in presence of a complex, a solid catalyst, and a reaction field forming material in a cathode by a production apparatus for performing electrolysis. In the complex, the solid catalyst, and the reaction field forming material, for example, a molybdenum complex expressed by Formula (A1-1) is used as the complex.




A platinum catalyst is used as the solid catalyst, and a rare earth metal-carbon-based binder is used as the reaction field forming material.

摘要： A method for producing ammonia involves producing ammonia from molecular nitrogen in a production apparatus for performing electrolysis by supplying electrons from a power source, protons from a proton source and molecular nitrogen from a device for supplying a nitrogen gas while in the presence of a solid catalyst and a complex in a cathode. For example, a molybdenum complex represented by formula (A1) or formula (B2) as the complex, and a platinum catalyst or a platinum catalyst/gold catalyst combination as the solid catalyst are used.
