Electrocatalytic Measurement Methodology of Oxide Catalysts Using a Thin-Film Rotating Disk Electrode
Suntivich, Jin; Gasteiger, Hubert A.; Yabuuchi, Naoaki; Shao-Horn, Yang (The Electrochemical Society, 2010-07)Transition-metal oxides can exhibit high electrocatalytic activity for reactions such as the oxygen reduction reaction (ORR) in alkaline media. It is often difficult to measure and compare the activities of oxide catalysts ... -
