Atomic-level insight about the metal–promoter interaction in Rh-based catalysts for the conversion of syngas to ethanol is provided. In the best-performing catalyst (Mn and Fe bi-promoted Rh on silica), the metal–promoter interaction leads to the formation of an active structure containing a bimetallic Rh–Fe alloy surrounded by MnOx species.
