Sulfated zirconia catalysts supported on SiO₂ and Al₂O₃ were prepared and studied. Phase composition of the catalysts, acidic properties in CO adsorption, and textural characteristics were assessed. Activity of the catalysts in isomerization of n-hexane was measured. Alumina was shown to be a promising support for the synthesis of such catalysts. A new step of additional sulfation after platinum deposition was proposed for the synthesis of alumina-supported catalysts. It was found that strong Lewis acid sites with CO absorption bands at 2210 and 2224 cm^-1 are formed in the catalysts. The yield of the sum of hexane isomers for the alumina-supported catalysts reached 80 wt.%.
