The nature of adsorbed reaction-intermediates and other surface species at catalyst surfaces is important in development of new uses for hydrocarbons and for increasing the efficiency of existing processes. To that end, adsorbed hydrocarbon and derivative layers formed on platinum, silver, and ruthenium surfaces in aqueous media were investigated as a function of electrode potential, pH, temperature, electrolyte, nature of the hydrocarbon, concentration of the hydrocarbon, and electrode surface structure. Data obtained during the project have identified fertile areas for practical development and have contributed to the framework for future basic research in the area. Important aspects of electrocatalytic processes are being studied, including: the most active surface structures, adsorbed intermediates, additives, electrolytic species and impurities; the reaction pathways of typical adsorbed hydrocarbon intermediates; and the fundamental causes of the influence of pH, potential, concentration, temperature and surface structure on electrocatalyst activity.
