Abstract: The present disclosure provides methods for fabricating catalysts for ammonia decomposition. The method may comprise (a) subjecting a catalyst support to one or more physical or chemical processes to optimize one or more pores, morphologies, and/or surface chemistry or property of the catalyst support; (b) depositing a composite support material on the catalyst support, wherein the composite support material comprises a morphology or surface chemistry or property; and (c) depositing one or more active metals on at least one of the composite support material and the catalyst support, wherein the one or more active metals comprise one or more nanoparticles configured to conform to the morphology of the composite support material and/or catalyst support material, thereby optimizing one or more active sites on the nanoparticles for ammonia processing.

Abstract: A method for ammonia decomposition is disclosed. The method may comprise providing a catalyst comprising an zirconia support and a layer adjacent to the support. The layer comprises a tetragonal phase comprising zirconium, cerium, and oxygen, an oxide of at least one of an alkali metal and a rare earth metal, and an active metal. The method may comprise bringing the catalyst in contact with ammonia at a temperature of from about 400° C. to 700° C. to generate a reformate stream comprising hydrogen and nitrogen at an ammonia conversion efficiency of at least about 70%. The method may comprise directing the hydrogen to generate electricity. The method may comprise generating heat for a reformer comprising the catalyst by combustion of gases or by electricity generated from hydrogen.
