Static and Dynamic Aspects of Chemisorption

  • Bengt I. Lundqvist


Theoretical results for molecular adsorption on metals are reviewed. A scenario for the chemisorption of H2 on Mg(0001) is presented, as inferred from calculated potential-energy surfaces and adsorbate-induced electron structure. Various steps of the chemisorption process, such as activated associative adsorption, trapping, precursor motion, and activated dissociative adsorption, are identified. A conceptual framework for the understanding of their characteristic properties, as well is of the specificity of adsorption and of the reactivity of metals, as described. Finally, it is stressed, how the study of vibrations at surfaces can give valuable information about the chemisorption process.
