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 with the microscopic coordinated structure properties, and identify the synergistic effect of…
