Abstract The electroreduction of CO 2 to high‐value products is a promising approach for achieving carbon neutrality. Among these products, formic acid stands out as having the most potential industrialization due its optimal economic value in terms consumption and output. In recent years, Faraday efficiency from has reached 90~100 %. However, this high selectivity cannot be maintained extended periods under currents meet industrial requirements. This paper reviews excellent work perspective catalyst stability, summarizing discussing performance typical catalysts. Strategies preparing stable highly active catalysts are also briefly described. review may offer useful data reference valuable guidance future design long‐stability

Mesostructure‐Specific Configuration of *CO Adsorption for Selective CO₂ Electroreduction to C₂₊ Products

Angewandte Chemie International Edition, Год журнала: 2024, Номер 64(1)

Опубликована: Сен. 2, 2024

The multi-carbon (C2+) alcohols produced by electrochemical CO2 reduction, such as ethanol and n-propanol, are considered indispensable liquid energy carriers. In most C-C coupling cases, however, the concomitant gaseous C2H4 product results in low selectivity of C2+ alcohols. Here, we report rational construction mesostructured CuO electrocatalysts, specifically mesoporous (m-CuO) cylindrical (c-CuO), enables selective distribution products. m-CuO c-CuO show similar towards total products (≥76 %), but corresponding predominant (55 %) (52 respectively. ordered mesostructure not only induces surface hydrophobicity, selectively tailors adsorption configuration *CO intermediate: prefers bridged adsorption, whereas favors top revealed situ spectroscopies. Computational calculations unravel that adsorbate is prone to deep protonation into *OCH3 intermediate, thus accelerating intermediates generate alcohols; contrast, apt undergo conventional process produce C2H4. This work illustrates via manipulation, paves a new path design efficient electrocatalysts with tunable key for targeted

Abstract The development of practical materials for (de)hydrogenation reactions is a prerequisite the launch sustainable hydrogen economy. Herein, we present design and construction an atomically dispersed dual‐metal site Co/Cu−N−C catalyst allowing significantly improved dehydrogenation formic acid, which available from carbon dioxide green hydrogen. active centers consist specific CoCuN 6 moieties with double‐N‐bridged adjacent metal‐N 4 clusters decorated on nitrogen‐doped support. At optimal conditions performance nanostructured material (mass activity 77.7 L ⋅ g metal −1 h ) up to 40 times higher compared commercial 5 % Pd/C. In situ spectroscopic kinetic isotope effect experiments indicate that promoted acid follows so‐called formate pathway C−H dissociation HCOO* as rate‐determining step. Theoretical calculations reveal Cu in moiety synergistically contributes adsorption intermediate raises d‐band center Co favor activation thereby lower reaction energy barrier.
