Figure 2
Oscillations in the white-line intensity were observed during fluctuating rates of carbon monoxide oxidation (a). Higher intensity indicates a larger fraction of distorted surface oxide relative to the low-activity carbon-monoxide-poisoned state. The relative amounts of catalyst with surface oxide (high rate) and catalyst poisoned with carbon monoxide (low rate) determine the overall rate of reaction (b). The amounts change over time and as function of position within the reactor. [From Singh et al. (2010bBB35). Copyright: ChemCatChem, 2010.]
