Zinc booster: A series of gold catalysts supported on ZnO-promoted CeO2–Al2O3 are applied in the purification of H2 streams through the water–gas shift reaction. The addition of ZnO promotes the activity of an Au/CeO2/Al2O3 catalyst. This increase in activity is mainly associated with the enhanced O2 storage capacity of the Zn-containing solids. The prepared catalysts tolerate start–stop cycles, showing potential for industrial application.
