TL;DR: In this paper, Boltammetry combined with singlepotential alteration infrared spectroscopy (SPAIRS) was used to study the extent of adsorbed CO produced at Pt, Ru and Pt-Ru alloy electrodes during methanol and formic acid oxidation in acidic supporting electrolyte.

TL;DR: In this article, carbon monoxide and deuterated water co-dosed onto Pt(111) at 110 K in ultrahigh vacuum (uhv) in comparison with coverage and potential-dependent infrared spectra for the analogous in situ Pt( 111)aqueous interface, the authors assess the manner and degree to which the former electrochemical modeling strategy mimics the vibrational spectral properties of the latter interface and exploit the additional molecular structural information obtainable for the former surface configuration in elucidating solvation effects for the in situ electrochemical system.

TL;DR: In situ infrared spectra are reported in the C-O stretching (ν CO )region for saturated CO adlayers on Pt(111) in four nonaqueous solvents; acetonitrile, dimethylformamide, dichloromethane, and tetrahydrofuran, each containing tetraalkylammonium cations, over wide electrode potential ranges, ca. −2.0 to 1.5 V vs SCE as discussed by the authors.

TL;DR: In this paper, infrared spectra in the CO stretching (νCO) region are reported for saturated CO adlayers on Pt(110) in various solvent media over wide (∼3 V) ranges of electrode potential in order to explore the influence of the surface potential in various ionic double-layer environments on the adsorbate bonding.
