Comparison of Pt/Ti-2 with Pt/SnO2 in catalyst properties revealed in the selective oxidation of CO run in the presence of H-2
The 1% Pt/TiO2 (50 m(2)/g) was comparable to 1% Pt/SnO2 (8.7 m(2)/g) in activity and both were more active than the 5.7% Pt catalysts. Hydrogen added, 5%, to the reaction mixt., 2.2% CO + 2.3% O-2 in He, made the catalysts and the supports more active A reaction mechanism was suggested, based on the reducibility and deg. of dispersion of the metal phase.
