In this work isotopic exchange of 18O2 with 16O and oxidation of C16O were investigated at 130°C on ceria-supported Au–CuO and Au–Co3O4 catalysts. Oxygen storage capacity (OSC) was measured at 400°C to check the influence of the metals in the catalysts, resulting in an enhancement of OSC for gold-containing catalysts compared to monometallic catalysts. The reactivity of surface oxygen atoms and the...
