Abstract
Surface resonance x-ray scattering, sensitive to the monolayer-level change of an oxidation state of a buried interface, is used for the investigation of electrochemical oxidation of Pt(111) single crystal surface. The strong ly Q-dependent energy scans through the L-III resonance energy of Pt atoms were accounted for by a large increase of the electron binding energy of th e surface atoms as a result of surface anodic oxidation.
