The effect of ZnO addition on H2O activation over Co/ZrO2 catalysts

- ZnO addition to Co/ZrO2 increased acetaldehyde selectivity and decreased acetone selectivity.
- ZnO addition to Co/ZrO2 inhibited Co oxidation via H2O.
- Showed clear trend correlating H2O dissociation activity and acetone/acetaldehyde selectivity.
