Applications of Interfacial Hydrogen Bond Network in Electrocatalytic Reactions

Abstract

Electrocatalytic conversion reactions of small molecules are core technologies for achieving sustainable energy conversion and environmental protection. The catalytic performance of these reactions is predominantly constrained by inefficient proton transport and suboptimal adsorption behavior of reaction intermediates at the catalyst-electrolyte interface. In recent years, modulating the interfacial hydrogen bond network to facilitate proton transfer processes and stabilize the adsorption of reaction intermediates in electrocatalytic reactions has garnered significant attention, with a growing body of related research. Rational regulation of the structure and connectivity of hydrogen bond network plays a pivotal role in enhancing the activity and selectivity of electrocatalytic reactions. This review systematically summarizes the latest advances in interfacial hydrogen bond network within the field of electrocatalysis. It first introduces current characterization techniques employed to investigate interfacial hydrogen bond network, followed by an in-depth analysis of core strategies for modulating such network. Subsequently, the critical applications of hydrogen bond network in electrocatalytic reactions are discussed. Finally, the challenges and future development directions of hydrogen bond network in practical applications are prospected.
