Effect of Surface Hydroxyl Groups on the Behavior of CO on Monoclinic Zirconia

The behavior of CO on ZrO₂ depends on the surface hydroxyl species. The effect of different hydroxylation treatments applied before CO adsorption on the zirconia will be presented. Temperature-programmed methods combined with microkinetic modeling and DRIFT spectroscopy are used to examine the amount and reactivity of the adsorbed surface species.
