Coverage dependent oxygen adsorption energies

What is it about?

Molecules adsorbed on a surface interact with each other and the interactions change as the concentration of molecules on the surface increases. We show that the intermolecular interactions for oxygen atom adsorbates are similar for a set of metal surfaces. This means one can predict the interactions of an adsorbate on a new metal surface from knowledge of the interactions on another surface.

This paper shows a principle of corresponding adsorption states for oxygen atoms on several late transition metal (111) surfaces. This means there is a common underlying mechanism that dictates how these adsorbates interact with the metal surfaces and with each other. The mechanism involves the metal d-bands, and we show that the adsorbates modify the surface d-band. Thus, the coverage dependence of the adsorption energy is surface mediated in this work.
