Indications for metal-support interactions: The case of CO2 adsorption on Cu/ZnO(0001)
Molecular beam scattering has been combined with TDS to provide consistent evidence for metal-support interactions (MSI). CO2 adsorbs on the Cu cluster and populated the perimeter of the clusters. The Cu-free areas of the support remain essentially clean. Hence, a synergistic effect such as MSI is present.
