| Popis: |
An apparatus was constructed to study catalytic reactions on one or more platinum single crystals in situ both at 1 atm total pressure and in high vacuum (10/sup -4/ to 10/sup -8/ torr). The main feature of the design is a novel movable bellows-cup mechanism by which the catalyst can be encased in a small volume for the high pressure experiments. Using this apparatus, the cyclopropane hydrogenolysis was investigated at 1 atm on a platinum stepped single crystal (Pt(s)-(6(111) x (100))) having a total surface area of 0.76 cm/sup 2/. Intial specific reaction rates were reproducible to about 10%, and to within a factor of 2 were identical to published values for this reaction on highly dispersed supported platinum catalysts. 5 figures, 4 tables. |
