Composition and structure of the RuO2(110) surface in an O2 and CO environment: Implications for the catalytic formation of CO2
TL;DR: In this article, the phase diagram of surface structures for the model catalyst in contact with a gas environment was calculated by density-functional theory and atomistic thermodynamics, and the importance of phase coexistence conditions was emphasized as these will lead to an enhanced dynamics at the catalyst surface.
