Electrochemical studies of carbon monoxide oxidation on platinum and platinum based fuel cell catalysts
… (CO) oxidation on surfaces of bulk platinum (Pt) and Pt based particle catalysts were conducted. Investigations focused on understanding relationships between surface characteristics of Pt electrodes and the oxidation kinetics of monolayer quantities of adsorbed CO. Cyclic voltammetry and …

Study of Faradaic Reactions Occurring At Polycrystalline Platinum Electrode Surfaces in Frozen, Aqueous Acidic Electrolyte
… (HOR), and oxygen reduction reaction (ORR) at polycrystalline Pt (Pt(poly)) in frozen and liquid aqueous H2SO4 electrolyte. The compared methods are: (i) linear sweep, in which a slowly varying overpotential (η) is applied, (ii) steady-state (SS) in which η is applied for t = 60 s to establish …

13C-nuclear-magnetic-resonance of carbon monoxide on platinum: Study of a highly dispersed catalyst
… on the surface layer of small particles of Pt metal have been observed by the method of spin echoes as a function of magnetic field, temperature, CO coverage and Pt dispersion. The samples are industrial catalysts: Pt supported on eta-alumina, with Pt dispersions ranging from 4% to 76%. …
