Abstract

Local spin density calculations are reported for interaction of atomic H with different palladium clusters (Pd4, Pd7 and Pd12) representing the Pd(110) surface. By scanning a two-dimensional potential energy surface for the H atom the pseudo-threefold site is found to be energetically favoured over the bridge site. At the equilibrium geometry the Pd-H distance is 1.8 Å. H-induced features in the electronic structure of the clusters are discussed and compared to the experimental results. Stabilizing H-H interactions are found for the zig-zag arrangement of the H atoms in which Pd 5s electrons play an important role.
