Abstract

A core@shell C/Cu@Co3O4 catalyst with interfacial-engineered nano-islands on a Cu substrate was constructed, featuring accelerated electron-transfer properties and optimized nitrate trapping through the synergetic interfacial effect, achieving a remarkable NH3 yield of 57.4 ± 2.9 mg h−1 mgcat−1 and...
