The products of the interaction of activated aluminum with water were used as a precursor of an oxide support of catalysts. The possibility of changing the composition of the oxide phase by varying the nature of the activator (gallium and Ga—In eutectic alloy) is shown. It was found that during the synthesis, gallium cations enter the structure of aluminum oxide by displacing aluminum from the tetrahedral position. The effect of gallium content in the composition of the support on its textural and acid-base properties is demonstrated. The presence of gallium in the composition of the catalyst leads to a modification of the catalytic properties of platinum, which consists in suppressing the hydrogenolysis of C—C bonds in the reaction of propane conversion. © 2020, Pleiades Publishing, Ltd.
