Abstract: The properties of the catalyst (Pt + Pr)/SiO2 prepared by decomposition of anchored complexes of Pr and Pt differ from those of Pt/SiO2 by (1) an increase in the dispersion and thermal stability of platinum, (2) a positive shift of the binding energy of the Pt 4f level by 0.6 eV, (3) a decrease in the specific chemisorption of H2 and a decrease in activity in benzene hydrogenation and ethane hydrogenolysis, but an increase in activity in the synthesis of methanol from CO and H2. The possible reasons for these effects are discussed on the basis of the concept of the direct interaction of Pt particles less than 10Å in size with surface Pr ions.
