Reduction Reactions versus Hydrogen
Proceedings of the Materials for Sustainable Development Conference (MATSUS Fall 24), 2023 A reduction reaction is half an overall electrochemical process and hydrogen evolution reaction (HER) is the simplest electrocatalytic reduction reaction. Beyond hydrogen, other reduction reactions are more complex with species involved, products formed, and selectivity typically changes as a function of catalyst and potential.
