Abstract

Abstract : The overpotential for H2 evolution from water can be rationally controlled by tuning the ligand-centered proton-coupled electron transfer (PCET) processes. Abstract : Two new nickel dithiolate derivatives have been examined for their electrocatalytic activity for the hydrogen evolution reaction (HER) in attempts to clarify whether the overpotential for the HER can be tuned upon varying the ligand-centered reduction potential that triggers the HER by the catalysts. We demonstrate the validity of this approach to achieve desirable tunability in the overpotential for the HER.
