Abstract:
The surface morphology and chemical composition of the MgAl- and MgGa-layered hydroxides as supports precursors were studied by SEM and EDX in all steps of the platinum catalysts Pt/Mg(Ga, Al)Ox synthesis. The study revealed a higher structural stability of Ga-containing samples in comparison with Al-containing analogs, which shows up as their morphological invariability during calcination, activation of layered double hydroxides, and anchoring of the metal complex. A similar Mg/M3+ ratio of metals estimated by both the volumetric method and EDX confirms that a uniform distribution of metals in the support is retained during the catalyst synthesis; this will ensure the specified adsorption and acid-base properties of Pt/MgAlOx and Pt/MgGaOx, which are the promising catalytic systems for dehydrogenation of light and higher alkanes.
