- •
Ag increases the reducibility of CeO2.
- •
Acetaldehyde is generated by ODH reaction.
- •
Adding Ag to CeO2 the oxidation rate of acetaldehyde to acetate increases.
- •
Adding Ag to CeO2 the selectivity to ethylene decreases.
- •
Ceria dissociates H2O, which provide oxidant species for its self re-oxidation.
