Abstract Electroreduction of carbon dioxide (CO 2 ) is a key strategy for achieving net‐zero emissions. Copper (Cu)‐based electrocatalysts have shown promise CO conversion into valuable chemicals but are hindered by limited C 2+ product selectivity due to competing hydrogen evolution and ineffective dimerization adsorbed intermediate ( * CO). Here, functional‐group‐directed reported enhance using single‐walled nanotubes (SWCNTs) as supports. The catalytic performance Cu nanoparticles strongly influenced the type density functional groups on SWCNTs. Optimized Cu/amine‐functionalized SWCNTs achieved Faradaic efficiency 66.2% partial current −270 mA cm −2 products within flow cell, outperforming Cu/SWCNTs Cu/cyano‐functionalized Density theory calculations revealed that electron‐donating amine can facilitate electron transfer from graphite sheet atoms, thereby shifting d‐band center upward. This shift enhances its hydrogenation derivative adsorption promotes water splitting, leading an increased tendency generation products. In situ infrared Raman spectroscopy confirm enhancement CHO coverage, facilitating C─C coupling. work provides molecular framework exploring interactions between active metals in electrolysis, offering insights designing catalysts broad range electrocatalytic processes.

Abstract The electrocatalytic conversion of CO 2 into valuable multi‐carbon (C 2+ ) products using Cu‐based catalysts has attracted significant attention. This review provides a comprehensive overview recent advances in catalyst design to improve C selectivity and operational stability. It begins with an analysis the fundamental reaction pathways for formation, encompassing both established emerging mechanisms, which offer critical insights design. In situ techniques, essential validating these by real‐time observation intermediates material evolution, are also introduced. A key focus this is placed on how enhance through manipulation, particularly emphasizing catalytic site construction promote C─C coupling via increasing * coverage optimizing protonation. Additionally, challenge maintaining activity under conditions discussed, highlighting reduction active charged Cu species materials reconstruction as major obstacles. To address these, describes strategies preserve sites control including novel utilization mitigation reconstruction. By presenting developments challenges ahead, aims guide future conversion.
