摘要：
The oscillatory behavior during CO oxidation over Cu foil has been observed in the temperature range of 350–750 °C. The oscillatory behavior occurred in CO excess similar to the well-known oscillations during CO oxidation over Ni and Co, but in contrast to the oscillations over Pt, Pd, Ir, and Ru. The periodic variation in oxygen imbalance together with variation in color changes during the oscillations and ex situ XRD measurements indicate that the oscillations were closely connected with the reversible oxidation of Cu to Cu2O. The oscillations were accompanied by propagation of oxidation and reduction wavefronts.
