Origin of copper dissolution under electrocatalytic reduction conditions involving amines

Chemical Science, vol. 15, pp. 14485–14496

Abstract

RHE or above. Our work provides a fundamental understanding of Cu dissolution facilitated by surface restructuring in amine solutions under electroreduction conditions, which is required for the rational design of durable Cu-based cathodes for electrochemical amination or other amine involving reduction processes.
