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.

Disclosed are shaped dehydrogenation catalysts, methods for making the catalysts, and methods for dehydrogenating a hydrocarbon using the catalyst. A method for making the shaped dehydrogenation catalyst can include combining a group 13 metal precursor and a group 1 metal precursor with a catalyst support precursor to form a shapeable material, shaping the shapeable material to form a wet shaped material, drying the wet shaped material to form a dry shaped material, and calcining the dry shaped material to form the shaped dehydrogenation catalyst.
