The aging step is performed for 3 at room temperature. The heating step is performed in an oil bath held at 100 degrees C. The method-II further comprises forming sulfonic acid functionalized zeolite FAU(Y) nanocrystals using the phenethyl functionalized zeolite FAU(Y) nanocrystals, by removing the tetramethylammonium organic template of the nanocrystals by an ion exchange process to form ion exchanged nanocrystals, and adding sulfonic acid groups to the ion exchanged nanocrystals by an acidification technique to form the sulfonic acid functionalized zeolite FAU(Y) nanocrystals. The ion exchange is process is performed by combining the phenethyl functionalized zeolite FAU(Y) nanocrystals with one of a 1M sodium nitrate or ammonium nitrate. The combining step comprises stirring while maintaining a temperature of 90 degrees C. The acidification comprises dealumination to increase the acid stability of the zeolite FAU(Y) nanocrystals by exchanging framework aluminum with silicon using an ammonium hexafluorosilicate (AHFS) treatment in a ammonium acetate buffered suspension, performed by dispersing the dealuminated, functionalized zeolite in a chlorinated solvent such as methylene chloride in an anhydrous atmosphere, followed by sulfonation of the phenethyl functionalized zeolite Y nanocrystals by combining them with trimethyl silyl chlorosulfonate in the chlorinated solvent suspension, followed by treating the nanocrystals with sodium methoxide to obtain their sodium form, which is then dispersed in dimethylformamide and converted to acid form by addition of hydrochloric acid. The aging is performed for 2 hours at room temperature. The heating is performed in an oil bath held at 100 degrees C for 2-7 days. The mixing step is performed for 1 hour at room temperature. The reacting step is performed by spinning the sealed combined solution within an environment held at 140 degrees C for 2 hours and fourteen days. The method-III further comprises forming sulfonic acid functionalized zeolite BEA nanocrystals using the phenethyl functionalized zeolite BEA nanocrystals, by acid treating the phenethyl functionalized zeolite BEA nanocrystals in a concentrated sulfuric acid environment, thus both removing the tetramethylammonium organic template of the nanocrystals, and adding sulfonic acid groups to the nanocrystals to form the sulfonic acid functionalized zeolite BEA nanocrystals.
