The Behavior of the Infrared Spectrum of Carbon Monoxide Adsorbed at Platinum Electrodes from Non-Aqueous Solvents
Abstract
Electrochemical oxidation of vanadium hexacarbonyl anion, V(CO)6 in aprotic solvents results in formation of the V(0) complex which decomposes to form Carbon Monoxide in high concentrations next to the electrode surface. As a result, CO is more rapidly adsorbed on the surface than by conventional methods. Surface reflection infrared spectroscopy shows that the potential dependent frequency shift for the infrared active bands due to CI adsorbed on platinum is 19/cm/V in 1,2-dichloroethane and 22/cm/V in acetonitrile, which are considerably less than the 30/cm/V observed in aqueous systems.
