a XPS spectra of Cos-SO-Ru in S 2p regions. b XPS spectra of Cos-SO-Ru and Cos-Ru in O 1 s regions. c XPS spectra of Cos-SO-Ru and Cos-Ru in Ru 3p regions. XANES spectra taken at d Ru and e Co K-edge. FT-EXAFS in R-space and corresponding fitting curves for f Ru foil, RuO2, Cos-SO-Ru and g Co foil, CoS, Cos-Ru, Cos-SO-Ru. All the original EXAFS data are processed without phase corrections. R represents the distance between the absorbing atoms and neighboring atoms, and χ(k) denotes the amplitude of the EXAFS oscillations as a function of photoelectron wavenumber k. Source data are provided as a Source Data file.
