Abstract: 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.

Abstract: A layered catalyst structure for purifying an exhaust gas stream includes a catalyst support and a palladium catalyst layer including an atomic dispersion of palladium ions electrostatically adsorbed onto an exterior surface of the catalyst support. The catalyst support includes an alumina substrate, a first ceria layer disposed on and extending substantially continuously over the alumina substrate, and a second colloidal ceria layer formed directly on the first ceria layer over the alumina substrate. The palladium catalyst layer is formed on the exterior surface of the catalyst support by applying a palladium-containing precursor solution to the exterior surface of the catalyst support and then heating the catalyst support and the palladium-containing precursor solution. The palladium-containing precursor solution includes a positively charged palladium complex in an aqueous medium and has a pH greater than a point of zero charge of the second colloidal ceria layer.
