A series of platinum catalysts were synthesized using Al2O3 supports modified with Na+ and Mg2+ cations (2 wt %). The phase compositions, textural properties, acidity, and catalytic performance of these catalysts in the non-oxidative dehydrogenation of propane were characterized by X-ray diffraction (XRD), low-temperature nitrogen adsorption–desorption, and temperature-programmed desorption of ammonia (NH3-TPD) and carbon dioxide (CO2-TPD). The catalytic activity decreased in the order: 2Mg/Al2O3 > Al2O3 > 2Na/Al2O3. The study demonstrates a correlation between the acid–base properties of the catalyst supports and the propane conversion pathway during dehydrogenation
