Abstract

Comparative studies on adsorption of atomic and molecular nitrogen indicate that in contrast to the previous results from tungsten bulk crystals, molecular chemisorption of N₂ is more stable than dissociative ones on tungsten anion clusters consisting of 8 atoms or less. Our result provides a new aspect in chemisorption on metal clusters, namely the energetically preferred channel of chemisorption - dissociative versus molecular - might be different for metal clusters and bulk surfaces.
