The Chemisorption Dynamics of Hydrogen on Metal Surfaces
The study of the dynamical aspects of the chemisorption on metal surfaces is relevant to such important physicochemical phenomena as heterogeneous catalysis, electrode processes, corrosion, etc. Dynamical studies can be performed by means of sophisticated experimental methods and of theoretical approaches, based on the development of ab initio and density functional techniques and on the enormous increase of computer power. Nowadays, it is possible to realize experiments in which well-collimated, ro-vibrationally cold, monoenergetic beams are used, and lasers are employed to produce reagent molecules in selected vibrational states and to detect state- and velocity-selected scattering products. The outcomes of these experiments can be directly compared with theoretical simulations of the chemisorption dynamics.
