Dynamics of carbon monoxide oxidation on palladium, platinum, and rhodium: Direct detection of excited rovibrational states in product carbon dioxide.

摘要

The dynamics of carbon monoxide oxidation by oxygen on polycrystalline palladium, platinum, and rhodium surfaces have been studied under nearly collision free conditions using infrared chemiluminescence of desorbed carbon dioxide as a probe of the structure of the transition state. The reactants were supplied to the catalyst surfaces through a free jet nozzle source and a Fourier transform infrared spectrometer operating at 0.012 cm
