The adsorbed states of CO on dispersed metals: A high-resolution solid-state NMR study.
01 January 1989
CO adsorbs on oxide-supported transition metals in three forms linear-bonded and bridged-bonded states on metal clusters and multicarbonyis on isolated single metal atoms. Recent broadline sup (13) C Nuclear Magnetic Resonance (NMR) studies of adsorbed CO have demonstrated the ability to provide quantitative site distributions, descriptions of the adsorbate bonding and geometry, models for adsorbate motions, and electronic properties of the metals. This study reports the high-resolution sup (13) C NMR spectra of CO adsorbed on silica-supported Rh and Ru obtained by magic-angle sample spinning which corroborate the broadline measurements and provide additional information.
