Реферат: Highly porous SiO2 supports with the MCM-41 structure were synthesized by a template method. The Pt–Ga catalysts for propane dehydrogenation were prepared using an impregnation method. The structure of the synthesized samples was studied by low-temperature nitrogen adsorption and X-ray diffraction (XRD) analysis, and the characteristics of catalyst reduction were studied by temperature-programmed reduction in hydrogen (TPR-H2). The catalytic properties were tested in the reaction of propane dehydrogenation, and the influence of a hydrogen additive to the reaction mixture on the activity of the catalysts was examined. The developed approach demonstrated the possibility of obtaining MCM-41-based materials characterized by an ordered mesoporous structure (mesopores of 3–4 nm in size) and a high specific surface area, which makes them promising for use as catalyst supports. It was found that the introduction of hydrogen into the reaction mixture led to an increase in the stability and activity of platinum catalysts.
