Insights into the function of silver as an oxidation catalyst by ab initio, atomistic thermodynamics
Wei-Xue Li, Catherine Stampfl, Matthias Scheffler
To help understand the high activity of silver as an oxidation catalyst, e.g., for the oxidation of ethylene to epoxide and the dehydrogenation of methanol to formaldehyde, the int…
