The structural characters and the electronic features of Pd-3 cluster
on the MgO(100) surface cluster were investigated by performing densit
y functional calculations. The geometric features of the cluster shape
of the Pd-3 cluster depended on the kinds of neighboring atoms intera
cting with the Pd atoms. The metal-support interatomic distance was co
mpared with experimental results and the quantitative consistency was
found. The dissociation of the Pd-3 cluster occurred, indicating the w
ay of the bond breaking of metal cluster. (C) 1998 Elsevier Science B.
