Abstract

An AuCu bimetallic nanourchin electrocatalyst, rich in low-coordinated Au/Cu atoms, achieves an impressive ∼100% faradaic efficiency (FE) for reduction of CO₂ to multicarbon (C₂₊) products, including 63.8% acetate and 36.2% ethanol at an ultralow potential of −0.4 V versus RHE. This work establishes a novel paradigm for the precise nanostructure engineering of AuCu bimetallic electrocatalysts toward efficient synthesis of high-value C₂₊ products.
