1. A process of forming a catalyst for aromatizing hydrocarbons, the process comprising:
enhancing a mesoporosity of a zeolite support by a base-leaching treatment, an acid-leaching treatment, or both to form a zeolite support having enhanced mesoporosity;
impregnating zinc or gallium on the zeolite support having enhanced mesoporosity to disperse the zinc or gallium on the zeolite support having enhanced mesoporosity, wherein the impregnating comprises:
mixing the zeolite support having enhanced mesoporosity with a solution containing zinc or gallium;
forming a slurry comprising the zeolite support having enhanced mesoporosity and the solution;
removing water from the slurry to form a paste; and
calcining the paste to form a zinc- or gallium-doped zeolite catalyst having a mesopore volume of greater than 0.09 cm3/g and less than 0.20 cm3/g.
