摘要： A method for catalytic synthesis of ammonia under normal pressures, including: performing a reaction of hydrogen and nitrogen to synthesize ammonia under normal pressures by taking a liquid alloy as a catalyst in a reactor, where the reactor contains a molten salt, the density of the molten salt is smaller than that of the liquid alloy, and the molten salt is used for providing a reaction interface and isolating the liquid alloy from being introduced impurities. The first metal can react with the nitrogen to produce the metal nitride, and the molten salt can provide a new reaction interface for the metal nitride to react with the hydrogen to synthesize the ammonia, so that the metal nitride can continuously generate the ammonia, and the synthesis of the ammonia can be effectively catalyzed. In addition, the molten salt can prevent the liquid alloy from contacting with the oxygen and the water vapor of the outside atmosphere, thereby preventing the liquid alloy from being oxidized and prolonging the service life of the liquid alloy.
