Particle size effects in the adsorption dynamics of CO: The structure–activity relationship in the case of Cu/Zn–ZnO

We provide evidence for particle size effects and shed light on the structure–activity relationship for the Cu-on-ZnO(0 0 0 1) system. The energy transfer processes governing the adsorption of CO depend distinctly on the morphology of the metal-on-metal oxide system as evident by impact energy dependent variations in the shape of the coverage dependent adsorption probabilities.
