The research aims to understand how different alkali cations influence the oxygen evolution reaction performance of nickel (oxy)hydroxide.
Comparison of hydroxide solutions (KOH, NaOH, LiOH) for their effects on oxygen evolution.
Analysis of activation energies related to each alkali cation.
Evaluation of performance metrics for oxygen evolution.
Demonstrated a clear activity order with KOH showing the highest performance followed by NaOH and LiOH.
Showed that larger cations reduce activation energies for oxygen evolution.
Indicated significant differences in efficiency based on the type of alkali cation.
Abstract
The OER performance of Nickel (oxy)hydroxide strongly depends on electrolyte cations. Here, we reveal a clear activity order of KOH > NaOH > LiOH with decreasing activation energies. Larger cations...
