Abstract The excessive CO 2 emissions from human activities severely impact the natural environment and ecosystems. Among various technologies available, electrocatalytic reduction is regarded as one of most promising routes due to its exceptional environmental friendliness sustainability. Covalent organic frameworks (COFs) are crystalline, porous networks that formed through thermodynamically controlled reversible covalent polymerization linkers via bonding. These materials exhibit high porosity, large surface area, excellent chemical thermal stability, sustainability, electron transfer efficiency, functionalization capabilities, making them particularly effective in reduction.

Abstract Electrochemical CO 2 reduction reaction (CO RR) offers a promising approach to close the carbon cycle and reduce reliance on fossil fuels. However, traditional decoupled RR processes involve energy‐intensive capture, conversion, product separation, which increases operational costs. Here, we report development of bismuth‐poly(ionic liquid) (Bi‐PIL) hybrid catalyst that exhibits exceptional electrocatalytic performance for conversion formate. The Bi‐PIL achieves over 90% Faradaic efficiency formate wide potential range, even at low 15% v/v concentrations typical industrial flue gas. biphenyl in PIL backbone affords hydrophobicity while maintaining high ionic conductivity, effectively mitigating flooding issues. layer plays crucial role as concentrator co‐catalyst accelerates kinetics. Furthermore, demonstrate catalysts solid‐state electrolyte (SSE) electrolyzer continuous direct production pure formic acid solutions from Techno‐economic analysis suggests this integrated process can produce significantly reduced cost compared approaches.

Abstract Significant efforts have been dedicated to the development of highly efficient electrocatalysts for electrochemical CO 2 reduction reactions (eCO RR). The outer coordination spheres catalytic centers may play a pivotal role in reaction pathway and kinetics eCO RR. Herein, three single copper sites coordinated Aza‐fused conjugated organic frameworks (Aza‐COFs‐Cu) with different around Cu are designed. Experiment density functional theory (DFT) calculation results reveal that redox non‐innocent significantly influence performance Aza‐COFs‐Cu When adjacent groups uncoordinated aromatic‐N quinone act as symmetry‐breaking sites, energy‐consuming activation process molecules can be accelerated via H + /e − transfer form *COOH intermediates, which will improve This study provides new perspective on design more advanced RR through engineering.
