Designing asymmetrical structures is an effective strategy to optimize metallic catalysts for electrochemical carbon dioxide reduction reactions. Herein, we demonstrate a transient pulsed discharge method instantaneously constructing graphene-aerogel supports asymmetric copper nanocluster catalysts. This process induces the convergence of atoms decomposed by chloride onto graphene originating from intense current pulse and high temperature. The exhibit atomic electronic due lattice distortion oxygen doping clusters. In reaction, selectivity activity ethanol production are enhanced structure abundance active sites on catalysts, achieving Faradaic efficiency 75.3% 90.5% multicarbon products at −1.1 V vs. reversible hydrogen electrode. Moreover, strong interactions between nanoclusters support confer notable long-term stability. We elucidate key reaction intermediates mechanisms Cu4O-Cu/C2O1 moieties through in situ testing density functional theory calculations. study provides innovative approach balancing stability asymmetric-structure energy conversion. Asymmetric show promise CO2 catalytic reduction. Here, authors develop prepare graphene-aerogel-supported Cu that enhance conversion into products.

The interaction of p-d orbitals at bimetallic sites plays a crucial role in determining the catalytic reactivity, which facilitates modulation charges and enhances efficiency CO2 electroreduction process. Here, we show ligand co-etching approach to create asymmetric Zn-Sn dual-atom (DASs) within metal-organic framework (MOF)-derived yolk-shell carbon frameworks (named Zn1Sn1/SNC). DASs comprise one Sn center (p-block) partially doped with sulfur Zn (d-block) N coordination, facilitating coupling between dimer. N-Zn-Sn-S/N arrangement displays an distribution atoms, leading stable adsorption configuration HCOO* intermediates. In H-type cell, Zn1Sn1/SNC exhibits impressive formate Faraday 94.6% -0.84 V. flow electronic architecture high accessibility, current density -315.2 mA cm-2 -0.90 Theoretical calculations ideal affinity lower reduction barrier, thus improve overall reduction.

Abstract CO 2 emissions and accumulation in the ecosystem have exacerbated climate change increased global temperature. This study focused on activation of hydrothermally synthesized Cu metal–organic framework (MOF‐199) with potassium citrate (C 6 H 5 K 3 O 7 ) to produce MOF‐derived carbon incorporated nano‐dispersed metallic oxidative species facilitate electrochemical reduction. Among all MOF samples, resulting carbon, activated by C , demonstrated highest electrocatalytic current lowest charge transfer resistance, achieving a Faradaic efficiency exceeding 50% for production acetic acid (CH COOH) at an applied potential − 1.1 V (vs RHE). The addition during preparation endowed mesoporous structure, thereby enhancing adsorption activation.
