Abstract

Pt-black samples were sintered in hydrogen at 473 and 633 K. Their surface composition and electron micrographic images are discussed together with their catalytic activity in reactions of n-hexane and methylcyclopentane. Pt-473 is more active in n-hexane reactions than Pt-633; also a different hydrogen pressure sensitivity is observed. Methylcyclopentane transformations show much less differences; thus these two reactants exhibit different structure sensitivities. Hydrocarbons and hydrogen compete for active sites, the availability and hydrogen content of which may be lower on the - more carbonized -Pt-633.
