Surface Electrochemistry of Metals
Abstract
The essence of this AFOSR project is to investigate the structure, composition, mode of attachment and reactivity of the molecular species which form at the surfaces of metals in contact with fluids. Progress to date includes advances in investigative technology, 110 scientific articles, and useful findings as follows: A series of new findings, advances in investigative technology and 105 scientific articles have occurred thus far. These include (1) determination of molecular orientations and modes of attachment at electrode surfaces; (ii) demonstration that mode of surface attachment affects electrochemical reactivity; (iii) exploration of the structure and composition of electrodeposited metal monolayers and thin-films; (iv) investigation of the nature of the species formed at electrode surfaces in ionic solutions; (v) adaptation of high-resolution electron energy-loss spectroscopy (HREELS) to measurement of vibrational spectra of species adsorbed at electrode surfaces; (vi) systematic HREELS, Auger and electrochemical studies of families of adsorbates, including acids, alcohols, alkenes, amines, mercaptans, phenols and pyridines; (vii) demonstration of the stability of chemisorbates in vacuum; (viii) development of techniques for measurement of complete Auger emission angular distributions potentially useful for structure probing of solid surfaces; (ix) development of an infrared (IR) reflectance spectrometer capable of recording the vibrational spectra of typical adsorbed organic molecules; and (x) studies of the interaction of the polar solvent acetonitrile with solid electrode surfaces.
