Abstract:Electrode potential-dependent NMR measurements of a $\sp{13}$C adsorbate on platinum were conducted for the first time. The method that I have developed has the capability of becoming a viable analytical technique in surface and solid-state electrochemistry. Using this method, carbon monoxide obtained from the decomposition of methanol was found to be bonded to a polycrystalline platinum electrode through linear and bridge configurations. Spin-spin and spin-lattice relaxation measurements were conducted to confirm the identification. Work completed previously by spectroelectrochemistry and gas-derived surface NMR measurements have been used for the data interpretation.
My thesis discusses the challenges of developing the surface NMR-electrochemistry method, as well as the solutions obtained to overcome them. Digitizing overload, RF penetration, vibrations, and the interfacing of electrochemistry to NMR are examined. Several second-generation probes, as well as computer simulations, were designed to expand the capabilities of this method. Analyses of a broad range of NMR spectra and cyclic voltammetry profiles of methanol-derived $\sp{13}$CO bonded to platinum are presented and discussed.
