Tailoring CO₂ Adsorption Configuration with Spatial Confinement Switches Electroreduction Product from Formate to Acetate

Journal of the American Chemical Society, Год журнала: 2025, Номер unknown

Опубликована: Фев. 5, 2025

Multi-proton-coupled electron transfer, multitudinous intermediates, and unavoidable competing hydrogen evolution reaction during CO2 electroreduction make it tricky to control high selectivity for specific products. Here, we present spatial confinement of Fe single atoms (FeN2S2) by adjacent FeS clusters (Fe4S4) orientate the transition adsorption configuration from C,O-side O-end, which triggers a shift activated first-step protonation C–C coupling, thus switching target product HCOOH in Faraday efficiency (FE: 90.6%) on FeN2S2 CH3COOH 82.3%) Fe4S4/FeN2S2. The strength *OCHO upon solitary site is linearly related coordination number Fe–S, with predominantly produced over single-atom (ortho-substituted S atoms). Fe4S4 cluster functions as switch reduction product, can not only optimize electronic structure neighboring but also impel complete hydrocarbon intermediate *CH3, followed coupling CO2* *CH3 via synergistic catalysis This strategy provides new avenue modulate reactant model desirable pathways, potential applications diverse multistep electrochemical processes controlled selectivity.

Abstract Synthesis of high‐loading atomic‐level dispersed catalysts for highly efficient electrochemical CO 2 reduction reaction (eCO RR) to ethylene (C H 4 ) in neutral electrolyte remain challenging tasks. To address common aggregation issues, a host‐guest strategy is employed, by using metal‐azolate framework ( MAF‐4 with nanocages as the host and dinuclear Cu(I) complex guest, form precursors pyrolysis into series nitrogen‐doped porous carbons (NPCs) varying loadings dual copper sites, namely NPC ‐Cu ‐21 (21.2 wt%), ‐11 (10.6 ‐7 (6.9 wt%). Interestingly, loading sites increased from 6.9 21.2 wt%, partial current density eCO RR yield C also gradually 38.7 93.6 mA cm −2 . In 0.1 m KHCO 3 electrolyte, at −1.4 V versus reversible hydrogen electrode vs RHE), exhibits excellent performance Faradaic efficiency 52% 180 Such can be attributed presence ultrahigh‐loading which promotes C─C coupling formation products.

Опубликована: Янв. 2, 2025

Catalytic transfer hydrogenation (CTH) strongly relies on the synergistic interaction between Lewis acid and base. Highly active, high-density, well-dispersed acid–base pairs (LP) are crucial to achieving efficient CTH catalysis, yet forming such an ideal interface remains challenging. To address this, a novel construction strategy is presented, which leverages regulation of layered double hydroxide (LDH) lattice structure establish LP interface. Supercritical isopropyl alcohol (SCIP) was employed selectively remove hydroxyl groups hydrogen bonds from NiAl-LDH surface, constructing rich MCUS Ni-OOH at LDH in simple, controllable, environmentally friendly way. The formation process SCIP analyzed using series dynamic characterization. Key factors restricting were identified by comparing results across different precursor preparation methods temperatures treatment. On this basis, one-pot reaction system established. Within system, catalyst ethyl levulinate (EL) γ-valerolactone (GVL) co-occur. simplifies exhibits ultrahigh catalytic efficiency, with GVL rate 0.780 molGVL·g–1·h–1.

ABSTRACT This annual review outlines the progress of carbon capture, utilization, and storage (CCUS) technologies in 2024. As human‐induced CO 2 emissions continued to rise, year presented critical challenges. Notably, 2024 was hottest on record first which global temperatures exceeded preindustrial levels by more than 1.5°C, driving intensified efforts advance CCUS. Scientific interest CCUS grew significantly, with number related publications increasing 11.4% compared 2023, reaching 53,970. The total operational commercial facilities also expanded, rising 16.3% a 50. In political area, governments introduced targeted policies accelerate adoption, focusing economic investment specific implementation requirements.
