Kunimatsu and published by . This book was released on 1986 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The carbon monoxide layer on a platinum electrode, which is adsorbed at 0.05 V relative to a normal hydrogen electrode (NHE) in 0.5l5 M sulfuric acid, and its oxidation to carbon dioxide at higher electrode potentials has been studied by both electrochemical and in-situ Fourier transform infrared reflection-absorption spectroscopy (FT-IRRAS). Polarization modulated FT-IRRAS was used to measured the vibrational spectra of adsorbed carbon monoxide as well as the evolved CO2 as a function of electrode potential. It is shown that the dominant surface species is linearly adsorbed CO, but that the bridge bonded species is oxidized first at about 0.20 V, giving rise to a decrease in the linear C-O stretching frequency of along with a broadening of the band. Oxidation of the linearly adsorbed CO begins at 0.35 V, producing a further, sharp decrease in the C-O stretching frequency as well as a considerable broadening of the band. It is concluded that the oxidation of the CO adlayer produced at 0.05 V occurs randomly throughout the adlayer, in contrast to oxidation at island edges, which is characteristic of CO adsorbed at 0.4 V. It is proposed that the difference in behavior of these two kinds of adsorbed CO is due to crystallographic modification of the platinum surface surface when the CO is adsorbed at 0.05 V in the hydrogen region which results in a higher density of bridge bonded CO.

Kunimatsu and published by . This book was released on 1984 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon monoxide adsorbed on a smooth platinum electrode was investigated in the potential range including the double layer region and the region of its steady state oxidation in solutions of 1M HClO4, H2SO4 or HCl using in situ polarization modulated Fourier transform - IR reflection absorption spectroscopy (FT-IRRAS). The intensity, position and linewidth of the IR absorption band of the linearly adsorbed CO species were measured as a function of potential. The evolution of carbon dioxide produced by the oxidation of the adsorbed CO was observed in situ by monitoring the IR absorption spectrum of the carbon dioxide. Oxidation of the adsorbed CO is completed before the formation of a surface oxide or an adsorbed oxygen layer. It was found that the linear increase of the CO stretching frequency continued even into the CO oxidation potential region where the coverage of CO decreases appreciably. It is concluded that oxidation proceeds mostly at the edges of CO islands where the water molecules are adsorbed adjacent to the CO sites. The band due to CO adsorbed in the bridged form was observed in 1M HClO4 by electrochemically modulated IR reflection spectroscopy (EMIRS) and it was concluded from its potential dependence that the bridged CO oscillator strength decreased at more positive potentials.

Book excerpt: Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.
