| Abstract: | High efficient Ce02 carrier is prepared by a simple method and a new type of catalyst Au/CeO2 is successfully prepared by deposition-precipitation. By characterization, we find that Au/CeO2 catalyst calcined under 500C temperature is high- est activity for CO oxidation, because gold particle size is appropriate and valence state is also consistent with the requirements of ca- talysis. On the other hand, the synergy effect is obvious between gold particles and Ce02 on Au/CeO2 catalyst calcined under 500~C temperature. |
