Use of platinum carbonyl complexes in the synthesis of Pt/MgAlO x catalysts

Pt/MgAlO x samples have been obtained by the adsorption of platinum carbonyl complexes on aluminum-magnesium oxides with Mg: Al = 2, 3, and 4. The composition of the adsorbed complexes has been determined. The catalysts synthesized from the carbonyl precursor show a higher activity in propane dehydrogenation and are less prone to deactivation than the catalysts prepared using platinum chloro complexes.
