Abstract The ever‐increasing concentration of atmospheric CO 2 , primarily driven by anthropogenic activities, has raised urgent environmental concerns, spurring the development carbon capture and utilization (CCU) technologies. This review focuses on integrated electrochemical conversion (ICECC), a promising approach that combines with its direct electroreduction into value‐added products. By eliminating energy‐intensive steps such as release, compression, transportation, ICECC offers more energy‐efficient cost‐effective alternative to conventional CCU methods. In this review, particular attention is given molecular electrocatalysts, which offer high tunability selectivity in reduction reaction (eCO RR). role capturing agents, including both external dual‐functional systems, critically examined understand their influence binding catalytic efficiency. Whereas significant potential, research area remains underexplored compared discusses mechanistic insights processes, highlighting key challenges potential future directions for improving catalyst design, enhancing efficiency, scaling up These developments can make critical component achieving neutrality addressing climate change.

Direct converting low concentration CO2 in industrial exhaust gases to high-value multi-carbon products via renewable-energy-powered electrochemical catalysis provides a sustainable strategy for utilization with minimized separation and purification capital energy cost. Nonetheless, the electrocatalytic conversion of dilute into value-added chemicals (C2+ products, e.g., ethylene) is frequently impeded by rate weak carbon intermediates' surface adsorption strength. Here, we fabricate range Cu catalysts comprising fine-tuned Cu(111)/Cu2O(111) interface boundary density crystal structures aimed at optimizing rate-determining step decreasing thermodynamic barriers adsorption. Utilizing engineering, attain Faradaic efficiency (51.9 ± 2.8) % partial current (34.5 6.4) mA·cm−2 C2+ feed condition (5% v/v), comparing state-of-art electrolysis. In contrast prevailing belief that activation ( $${{CO}}_{2}+{e}^{-}+\, * \,\to {}^{ }{CO}_{2}^{-}$$ ) governs reaction rate, discover that, under conditions, shifts generation *COOH $${}^{ } {{CO}}_{2}^{-}+{H}_{2}O\to {COOH}+{{OH}}^{-}({aq})$$ Cu0/Cu1+ boundary, resulting better production performance. The development operate resembling waste holds promise reduction. authors report vacuum calcination approach regulating on Cu-based can electro-catalyze low-concentration CO2.

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.

The electrochemical reduction of carbon dioxide (CO2) to produce fuels and chemicals has garnered significant attention. However, achieving control over the selectivity resulting products remains a challenging task, particularly within molecular systems. In this study, we employed silver complex immobilized on graphitized mesoporous (GMC) as catalyst for converting CO2 into CO, an impressive 90% at −1.05 V vs RHE. Notably, newly formed nanoparticles emerged active sites responsible high CO rather than system. Intriguingly, introduction copper ions restructured Ag-nanoparticle-decorated altered product selectivity. At −1.1 RHE in 0.1 M KCl, achieved C2 75%. Furthermore, not only Ag–Cu bimetallic nanoparticle but also small-sized nanocluster decorated GMC was proposed during catalytic reactions. Our straightforward approach offers valuable insights fine-tuning systems, extending beyond C1 products.
