CO‐Adsorption on MgO Revisited: Polarization‐Resolved Identification of Step Edges as the Dominant Defects on MgO(100) and MgO(110)

ABSTRACT Magnesium oxide is a paradigmatic ionic oxide, yet its experimentally observed chemical activity remains difficult to reconcile with its wide band gap and non‐reducible character. Here, we combine polarization‐dependent infrared reflection–absorption spectroscopy with hy...
