Cu-based catalysts hold promise for electrifying CO2 to produce methane, an extensively used fuel. However, the activity and selectivity remain insufficient due lack of catalyst design principles steer complex reduction pathways. Herein, we develop a concept carbon-supported Cu by regulating active sites' atomic-scale structures engineering carbon support's mesoscale architecture. This aims provide favorable local reaction microenvironment selective pathway methane. In situ X-ray absorption Raman spectroscopy analyses reveal dynamic reconstruction nitrogen hydroxyl-immobilized Cu3 (N,OH-Cu3) clusters derived from atomically dispersed Cu–N3 sites under realistic conditions. The N,OH-Cu3 possess moderate *CO adsorption affinity low barrier hydrogenation, enabling intrinsically CO2-to-CH4 compared C–C coupling with high energy barrier. Importantly, block copolymer-derived fiber support interconnected mesopores is constructed. unique long-range mesochannels offer H2O-deficient prolong transport path CO intermediate, which could suppress hydrogen evolution favor deep toward methane formation. Thus, newly developed consisting in constructed embedded into bicontinuous achieved unprecedented Faradaic efficiency 74.2% at industry-level current density 300 mA cm–2. work explores effective concepts steering desirable pathways interfacial catalytic systems via modulating site atomic level pore architectures supports on create microenvironments.

Abstract The conversion of carbon dioxide (CO 2 ) into value‐added chemicals with two or more carbons (C 2+ is a promising strategy that cannot only mitigate anthropogenic CO emissions but also reduce the excessive dependence on fossil feedstocks. In recent years, atomically dispersed metal catalysts (ADCs), including single‐atom (SACs), dual‐atom (DACs), and single‐cluster (SCCs), emerged as attractive candidates for fixation reactions due to their unique properties, such maximum utilization active sites, tunable electronic structure, efficient elucidation catalytic mechanism, etc. This review provides an overview significant progress in synthesis characterization ADCs utilized photocatalytic, electrocatalytic, thermocatalytic toward high‐value C compounds. To provide insights designing chemical originating from , key factors influence activity selectivity are highlighted. Finally, relevant challenges opportunities discussed inspire new ideas generation ‐based products over ADCs.
