We present calorimetric measurements of the effect of cluster size on the adsorption enthalpy of carbon monoxide on Pd nanoclusters sized from 120 to 4900 Pd atoms per particle, which were grown in situ on a well-ordered Fe3O4/Pt(111) film. A substantial decrease in the initial heat of adsorption amounting to about 20–40 kJ mol−1 was observed on the smallest Pd nanoparticles as compared to the larger Pd clusters and the extended Pd(111) single-crystal surface. We discuss this effect in terms of the size-dependent properties of the Pd nanoparticles.
