The dissociation of diatomic molecules at surfaces
TL;DR: In this article, the authors present an exposition of the various theoretical models currently in use for describing the dynamics of molecular dissociation at surfaces and the methods that have been developed for treating the dissipative motion as the molecule nears the surface are presented.

Eley–Rideal reactions between H atoms on metal and graphite surfaces: The variation of reactivity with substrate
Bret Jackson,Didier Lemoine +1 more
TL;DR: In this article, the reaction of gas-phase H atoms with H atoms adsorbed onto a variety of substrates was shown to exhibit a wide range of reactivity, and the single-collision Eley-Rideal reaction cross sections are generally small, suggesting that hot-atom processes play an important role in H2 formation on metal surfaces.

A model potential for chemisorption: H2+W(001)
TL;DR: In this paper, a potential function to describe the interaction of a diatomic molecule with a solid surface is formulated as a modified LEPS potential, and the surface is approximated by a rigid background potential, periodic in the plane of the surface.
