Cu–Zn–Al and Cu–Ce–Zr mixed oxide catalysts were prepared by two different methods, co-precipitation and flame spray pyrolysis. The performance of the catalysts was evaluated using the water-gas shift reaction with and without CO2 and H2 added to the feed. Cu–Ce–Zr catalysts are found not to be superior to Cu–Zn–Al catalysts in terms of initial activity and short-term stability. Their apparent activation energy appears to be less affected by increased concentrations of CO2 and H2.
