Synthesis, Structure and Reactivity of Molecules Attached to Electrode Surfaces.
Abstract
This project was to determine the structure, orientation, composition and reactivity of the surface molecular species which form spontaneously when metals come into contact with fluids, as in batteries, fuels cells, electronic circuits, marine environments and the atmosphere. These include: determination of the spatial orientations and mode of attachment of typical organic molecules chemically bonded to electrode surfaces; discovery that each orientation of an adsorbed molecule reacts differently; identification and exploration of variables which influence adsorbate orientation (concentration, temperature, potential, electrolyte, solvent, substrate, surface structure, pH and hydrogen bonding); exploration of the influence of oriented adsorbates on electrode rates; preparation of well-defined surfaces under atmospheric conditions; electrodeposition of highly ordered layers of Ag and Cu onto well-defined substrates; discovery of the orderedness of adsorbed ionic layers at well-defined surfaces; direct experimental exploration of the cation-selectivity of metal-solution surfaces. These findings were made possible by a unique combination of surface research techniques in ultra-high vacuum and electrochemistry in solution, employed in a long-term systematic series of investigations.
