ABSTRACT OF THE DISCLOSURE A catalyst for electrochemical ammonia synthesis incudes a carbon carrier composed of carbon; and 20-65 wt% of iron, copper and sulfur, based on weight of the carbon, supported in the carbon carrier. The catalyst may be coated on an electrode selected from the group consisting of carbon paper, carbon cloth, carbon felt, fluorine- doped tin oxide (FTO) conducting glass, and combinations thereof by spray coating, screen printing or ink jet printing. The catalyst has an ammonia synthesis activity up to several times to several tens of times of the activity of the existing single metal or metal oxide catalysts. Thus, when using the catalyst, it is possible to provide a method for electrochemical ammonia synthesis having an improved ammonia production yield and rate.
