Adsorption of alkanes and alkenes on Pt as studied by work function changes
Abstract
Adsorption of methane, ethane, propane, neopentane, ethene and propene has been studied on polycrystalline Pt between 323 and 573 K. The adlayer was stable in vacuum up to 473 K. The H2 partially removed the adlayer below 450 K and stabilized it above 500 K.
