It is proposed to determine the identity and electrochemical reactivity of the species present at electrocatalyst surfaces after pretreatment and use in solutions of hydrocarbons. A representative selection of hydrocarbons will be studied including potential fuels, intermediates, products, catalyst modifiers, solvents, electrolytes and poisons. Electron energy-loss (EELS) spectra have been obtained of organic molecules adsorbed from aqueous electrolytes on Pt single crystal surfaces. Reduction products from adsorbed organic sulfur compounds at polycrystalline Pt electrodes were identified. Electrocatalytic oxidation of aromatics was also studied, as was bromine adsorption at Pt electrodes and metallization of electrocatalyst surfaces. (CBS)
