Superior electrocatalytic hydrogen evolution activity of a triply bridged diruthenium(ii) complex on a carbon cloth support

Abstract

This article describes the structural authentication of a unique triply bridged [1](ClO4)2 and monomeric [2]ClO4/[3]ClO4. Electrochemical HER on a carbon cloth support demonstrated the superior performance of [1](ClO4)2 with high TON (>105) and its long-term stability. The primary kinetic isotope effect of [1](ClO4)2 revealed the involvement of PCET in the rate-determining step. © 2024 The Royal Society of Chemistry.
