Abstract

The adsorption of CO on amorphous silica–alumina (ASA) was calculated by DFT. CO appears as a probe of the electrostatic field induced by the whole surface, at the origin of a so-called vibrational Stark effect responsible for the CO frequency shifts. Brønsted acidity of the ASA sites does not directly correlate CO frequency shifts.
