To evaluate electrochemical measurement techniques for determining electrode kinetics during the hydrogen evolution reaction when competing reactions from trace impurities interfere.
Assessed electrochemical kinetic measurement procedures across copper, gold, molybdenum, palladium, rhodium, and iron electrodes.
Analyzed the impact of solution-phase trace impurities and competing electrochemical reactions on kinetic parameter determination.
Identified critical technical factors required to isolate hydrogen evolution kinetics from background impurity reactions across multiple metal substrates.
Characterized experimental conditions necessary to minimize measurement distortion during electrocatalytic kinetic evaluations.
Abstract
Various aspects of technique in measurements of electrode kinetics under conditions where competing reactions due to the presence of trace impurities in the solution are important are examined.
