Size-effect induced controllable Cu⁰-Cu⁺ sites for ampere-level nitrate electroreduction coupled with biomass upgrading.

ABSTRACT: The synergistic Cu⁰-Cu⁺ sites is regarded as the active species towards NH₃ synthesis from the nitrate electrochemical reduction reaction (NO₃^-RR) process. However, the mechanistic understanding and the roles of Cu⁰ and Cu⁺ remain exclusive. The big obstacle is that it is challenging to effectively regulate the interfacial motifs of Cu⁰-Cu⁺ sites. In this paper, we describe the tunable construction of Cu⁰-Cu⁺ interfacial structure by modulating the size-effect of Cu₂O nanocube electrocatalysts to NO₃^-RR performance. We elucidate the formation mechanism of Cu⁰-Cu⁺ motifs by correlating the macroscopic particle size wi
