The state of supported metals in copper-platinum-alumina catalysts (0.15 at % Pt, 2 and 7.5 at % Cu), which differ in the preparation method and pretreatment conditions, is studied by diffuse-reflectance IR spectroscopy using CO adsorption. The activity of the catalysts in propane dehydrogenation is studied. The propylene yield is shown to depend on the concentration of Pt atoms. Also, partial hydrogenolyisis of propane and prolpylene occurs resulting in C{sub 1}-C{sub 2} hydrocarbons. These Pt atoms are assumed to be responsible for the activity of the catalysts in the reaction of propane dehydrogenation.
