Photoelectron spectroscopy has been used to detect gas-phase organic radicals as well as stable products formed in low-pressure gas-surface reactions.The products were sampled directly after exiting the catalyst bed.Allylic hydrogen abstraction by Bi2O3 at 760 degC forms gas-phase allyl and 2-methylallyl radicals from propylene and isobutylene, respectively, in the presence of oxygen.CO2 and H2O are the other observed products of alkene oxidation over Bi2O3.The product distributions and the 2-methylallyl radical yields as a function of oxygen pressure and Bi2O3 temperature are discussed.
