    Abstract

    On-stream deactivation during a water gas shift (WGS) reaction over gold supported on a ceria-zirconia catalyst was examined. Although the fresh catalyst has very high low temperature (250 °C. This process reduces the metal-support interaction, which is considered to be critical in determining the high activity of the catalyst.
