The initial chemisorption of O 2 and CO on small copper clusters in the range from six to nine atoms has been investigated using a self-consistent jellium description of the clusters. The calculations were performed within the local-density approximation expanding the wave functions in a linear combination of atomic and spherical jellium orbitals. The results indicate a strong size dependence in the chemisorption energies. O 2 was found to be most strongly bound to the Cu 9 cluster while COCu 6 was the most stable product in the case of CO chemisorption. The observations are consistent with experiments and the underlying reasons were traced to differences in cluster-adsorbate hybridization and charge-transfer mechanisms.
