Abstract

Abstract The electrochemical CO 2 reduction reaction (CO 2 RR) exhibits significant potential to efficiently convert CO 2 into ethylene (C 2 H 4 ). However, achieving high C 2 H 4 selectivity remains a considerable challenge due to the difficulty in effective C─C coupling and stringent requirements on CO 2 purity. Herein, a novel contact‐electro‐catalysis method for CO 2 RR is presented by constructing dual‐active‐site catalysts on the electronegative tribolayer of a triboelectric nanogenerator (TENG), including single copper atom anchored polymeric carbon nitride (Cu─PCN) and CuO nanoparticle, achieving an outstanding C 2 H 4 Faradaic efficiency of 63.5% in dilute CO 2 . Experimental and theoretical studies indicate that Cu─PCN active sites exhibit the ability to heighten * H adsorption and facilitate its migration into CuO nanoparticles. This process effectively modulates the coverage of * H on CuO and promotes the transformation of * CO into * CHO. Subsequently, * CHO undergoes dimerization on the CuO surface, ultimately yielding C 2 H 4 . Furthermore, the electric field generated by the TENG enhances the coverage of * H and * CO on both the Cu─PCN and CuO surfaces, which subsequently reduces the energy barrier for C─C coupling. This work provides a new route to enhance the selective reduction of CO 2 to C 2 H 4 by integrating contact electrocatalysis with dual active site technologies.
