Description
Summary:The different observations concerning the platinum-like electronic structure found in X-ray photoelectron spectra as contrasted by the platinum-unlike density of states detected by soft X-ray appearance potential spectroscopy is reconciled. The platinum-like catalytic activity of WC results from changes in the electron distribution when C is added to W; core level chemical shifts indicate electron transfer from W valence orbitals to C 2p orbitals.
