WebbAlthough double-layer charging corrections to results of charge-transient and cyclic voltammetry current responses are required in experiments conducted at oxidized Pt electrodes, little information is available on the interfacial double-layer capacitance at such surfaces. Problems have arisen in both electro-reflectance and nanogravimetry studies … WebbThe effects of surface segregation on the oxygen reduction reaction (orr) have been studied on a polycrystalline Pt 3 Ni alloy in acid electrolyte using ultra high vacuum (UHV) surface sensitive probes and the rotating ring disk electrode (RRDE) method. Preparation, modification and characterization of alloy surfaces were done in ultra high vacuum (UHV).
