Ionic liquids (ILs) , such as [BMIM][Tf 2 N], on well‐defined SCILL model catalysts are able to replace weakly adsorbed CO. On Pt, on‐top CO remains adsorbed under the ionic liquid layer, but its IR signal red‐shifts by over 30 cm −1 . IL–adsorbate interactions are mediated by the noble metal and similar to ligands.
