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

Abstract The development of effective strategies to enhance the activity and selectivity Cu‐based catalysts for CO 2 reduction reaction (CO RR) remains a critical challenge, particularly on relatively inert Cu facets that are highly active in competitive hydrogen evolution (HER). In this study, series Cu‐M (M = Au, Ag, Pd) bimetallic tandem interfaces fabricated nanocolumn arrays (Cu NCAs) with predominantly exposed (200) facets. These excited significant number + species modulated adsorption behavior intermediates RR, resulting improved RR substantial HER. Notably, Cu‐Au, Cu‐Ag, Cu‐Pd NCAs displayed excellent C H 4 , CO, HCOOH products, optimized faradaic efficiency (FE) ≈43.2, ≈48.0, ≈50.7%, respectively. According situ spectroscopic analysis, each interface exhibited distinct catalytic pathways: Cu‐Au favored *COOH *CO followed by C‐C coupling production, Cu‐Ag promoted desorption generation, facilitated *OCHO formation production. This study provides strategy design high‐performance more practical electrodes directly modifying various commercial substrates.
