Abstract:
We report XANES L-edge measurements of a precisely defined Cu₁/Fe₃O₄(001) model single-atom catalyst. The spectrum acquired from the 2-fold coordinated Cu adatoms strongly resembles that of bulk Cu₂O, with the addition of a pre-edge feature at 931 eV. We show that this feature arises from the adsorption geometry of the Cu adatom and is enhanced by the structural deformation induced by CO adsorption.
