Characterization of Silicotungstate Anion Modified Metal Surfaces

221 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2001.Multilayer-like features were observed on Ag surfaces when the potential was cycled negative of the onset of the first redox couple of alpha-H 4SiW12O40. QCM measurements suggested that negative potentials attracted alpha-SiW12O404- near Ag surfaces. XPS data qualitatively indicated that more alpha-SiW 12O404- was on Ag surfaces after potential cycle treatment. The multilayer-like features of alpha-H4SiW 12O40 on Ag surfaces were also suggested by X-ray specular reflectivity and STM measurements.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
