The electron-oxidation of CO at the Ru(0001) single-crystal electrode surface

Article Abstract:

In situ FTIR spectroscopic and electrochemical data and ex situ (emersion) electron diffraction and Auger spectroscopic data are presented with respect to electro-oxidation of CO of the Ru(0001) single-crystal surface in perchloric acid solution. The data obtained from the Ru(0001) electrode are in marked contrast to those observed on polycrystalline Ru, where only linear CO is observed.

Electrocatalytic activity of Ru-modified Pt(111) electrodes toward CO oxidation

Article Abstract:

A study conducted the first surface structural characterization and the coverage determination of Ru-modified Pt(111) electrodes using Auger electron spectroscopy and two electron diffraction methods. It also examined the catalytic activity of these electrodes toward carbon monoxide electrooxidation by cyclic voltammetry and in situ Fourier transform infrared spectroscopy. Experimental methods, findings and conclusions are discussed.
