Abstract

The green electricity-driven electrocatalytic reduction of organic compounds in aqueous solution has merged as a sustainable and green platform for organic electrosynthesis, upcycling of chemical waste, and environmental remediation. Compared with the thermocatalytic hydrogenation process, the electrocatalytic reduction of organic compounds uses water as a proton source, which enables its operation at ambient conditions with simplified reaction schemes and significantly reduces operation cost and energy consumption. Most studies have demonstrated the development of electrocatalysts to boost the current efficiency, conversion, and product selectivity of the electrocatalytic reduction processes. Still, little attention has been paid to the mechanism (e. g., electron/proton transfer route) and related energetics behind the electrocatalytic reduction process. This Concept overviews the recent development of the electrocatalytic reduction systems for environmental remediation, pollutant upcycling, and valorization of biomass-derived chemicals. This Concept highlights the underlying mechanisms and aims to provide instructive guidance on designing efficient and selective electrocatalytic systems.
