In situ potential difference Fourier transform infrared reflection absorption spectroscopic studies of the electrochemical oxidation of adsorbed carbon monoxide on nickel in alkaline solutions

摘要: The spectral properties of CO adsorbed on polycrystalline nickel electrodes in 0.1 M KOH have been examined using situ potential difference Fourier transform infrared spectroscopy. results obtained shown that the voltammetric peak observed first linear scan positive direction for Ni(poly)/CO(ads) surfaces prepared by a special procedure is associated with electrochemical oxidation bridge-bond to generate solution-phase carbonate as only detectable product. No changes stretching frequency (ν ) could be found function region negative onset
