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:
