- Additional information
- Water has been shown for the first time to act as the main oxidant for the CO oxidation reaction even in the presence of gas phase oxygen. This surprising result has significant consequences for the modelling and prediction of the activity of car exhaust catalysts which prior to this study would have used the CO+O2 reaction as one of the predominant reactions. It also provides a new design parameter to improve the activity of these systems where the activation of water is the critical step rather than dissociation of oxygen.
