Abstract

B-Doped oxide-derived-Cu is a highly efficient electrocatalyst for transformation of CO₂ to C2 products. The faradaic efficiency of C2 products could reach 48.2%, with a high current density of 33.4 mA cm⁻² at low potentials in 0.1 M KHCO₃ electrolyte. The excellent performance of the catalyst is mainly attributed to Cu⁺ species stabilized by the introduction of B.
