A method of manufacturing a catalyst includes mechanochemically processing an input material to generate a processed material, where the input material comprises a support and loading the processed material with a loading material. The support is a zeolite, a Beta zeolite, or a H-Beta zeolite and the loading material comprises nickel (Ni) or nickel-copper (NiCu). Lanthanum oxide (La.sub.2O.sub.3) is a promoter for the catalyst. A first interface of a NiCu/La-zeolite catalyst is generated when the loading material further includes the promoter; and a second interface of a NiCu/La-zeolite catalyst is generated when the input material further includes the promoter.
