Her kinetics
Witryna17 lip 2014 · This communication reports on hydrogen evolution reaction (HER), studied at Ni foam and Pd-activated nickel foam materials in 0.1-M NaOH solution over the temperature range of 20–60 °C. Catalytic modification of Ni foam leads to significant facilitation of temperature-dependent HER kinetics, manifested through radically … WitrynaIn this work, we study how the cation identity and concentration alter the kinetics of the hydrogen evolution reaction (HER) on platinum and gold electrodes. A previous work suggested an inverted activity trend as a function of alkali metal cation when comparing the performance of platinum and gold catalysts in alkaline media. We show that …
