Abstract

The reaction of CO₂ on the vicinal Cu(997) surface at 340 K under CO₂ gas pressure of 0.8 mbar was investigated by ambient pressure X-ray photoelectron spectroscopy. A main reaction product on the surface was identified as carbonate (CO₃), based on estimation of the composition ratio of oxygen to carbon. CO₃ was produced on the surface through the reaction of CO₂ with oxygen formed from CO₂ dissociation. The amount of adsorbed CO₃ was increased and saturated as time elapsed. After saturation of adsorbed CO₃, atomic oxygen appeared on the surface, indicating that CO₂ dissociation into CO and O continued to take place. The present study shows the importance of CO₃ intermediate in the CO₂ chemistry on stepped Cu surfaces.
