Carbon peaking and carbon neutralization trigger a technical revolution in energy & environment related fields. Development of new technologies for green production storage, industrial saving efficiency reinforcement, capture, pollutant gas treatment is highly imperious demand. The emerging porous framework materials such as metal–organic frameworks (MOFs), covalent organic (COFs) hydrogen-bonded (HOFs), owing to the permanent porosity, tremendous specific surface area, designable structure customizable functionality, have shown great potential major energy-consuming processes, including sustainable catalytic conversion, energy-efficient separation storage. Herein, this manuscript presents systematic review global comprehensive applications, from macroscopic application perspective.

Electrochemical Carbon Dioxide Reduction to Ethylene: From Mechanistic Understanding to Catalyst Surface Engineering

Nano-Micro Letters, Год журнала: 2023, Номер 15(1)

Опубликована: Июль 11, 2023

Electrochemical carbon dioxide reduction reaction (CO2RR) provides a promising way to convert CO2 chemicals. The multicarbon (C2+) products, especially ethylene, are of great interest due their versatile industrial applications. However, selectively reducing ethylene is still challenging as the additional energy required for C-C coupling step results in large overpotential and many competing products. Nonetheless, mechanistic understanding key steps preferred pathways/conditions, well rational design novel catalysts production have been regarded approaches achieving highly efficient selective CO2RR. In this review, we first illustrate CO2RR (e.g., adsorption/activation, formation *CO intermediate, step), offering conversion ethylene. Then alternative pathways conditions competitive products (C1 other C2+ products) investigated, guiding further development generation. Engineering strategies Cu-based CO2RR-ethylene summarized, correlations mechanism/pathways, engineering selectivity elaborated. Finally, major challenges perspectives research area proposed future practical

Enhancing CO₂ Electroreduction to Ethylene via Copper−Silver Tandem Catalyst in Boron‐Imidazolate Framework Nanosheet

Advanced Energy Materials, Год журнала: 2023, Номер 13(19)

Опубликована: Март 31, 2023

Abstract Copper‐based tandem catalysts with a well‐defined Cu coordination environment for the electrochemical CO 2 reduction reaction (CO RR) are highly desirable, due to their unique geometric‐electronic properties and helpfulness revealing structure–property correlations. Here, this work synthesizes catalyst at atomic configuration scale, Ag@BIF‐104NSs(Cu), by using ultrathin boron imidazolate framework (BIF) nanosheets as support load Ag nanoparticles (NPs). Due ordered benzoate ligands decorated on sites of BIF‐104NSs(Cu), NPs located in proximity via effect. Electrochemical RR measurements show improves selectivity activity ethylene. The faradaic efficiency (FE C2H4 ) 21.43% is significantly higher than that BIF‐104NSs(Cu) (3.82%). Further, density functional theory calculations reveal composite can efficiently reduce *CO, subsequently migrate sites. Thereafter, Cu–Ag atom pair responsible C–C coupling local enriched *CO further formation C H 4 .

A Bismuth‐Based Zeolitic Organic Framework with Coordination‐Linked Metal Cages for Efficient Electrocatalytic CO₂ Reduction to HCOOH

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(45)

Опубликована: Сен. 18, 2023

Zeolitic metal-organic frameworks (ZMOFs) have emerged as one of the most promsing catalysts for energy conversion, but they suffer from either weak bonding between cubes (MOCs) that decrease their stability during catalysis processes or low activity due to inadequate active sites. In this work, through ligand-directing strategy, we successfully obtain an unprecedented bismuth-based ZMOF (Bi-ZMOF) featuring a ACO topological crystal structure with strong coordination Bi-based cages. As result, it enables efficient reduction CO2 formic acid (HCOOH) Faradaic efficiency high 91 %. A combination in situ surface-enhanced infrared absorption spectroscopy and density functional theory calculation reveals Bi-N contributes facilitating charge transfer N Bi atoms, which stabilize intermediate boost HCOOH. This finding highlights importance environment metal sites on electrocatalytic reduction. We believe work will offer new clue rationally design zeolitic MOFs catalytic reaction.

Journal of the American Chemical Society, Год журнала: 2024, Номер 146(1), С. 1144 - 1152

Опубликована: Янв. 2, 2024

It is crucial to achieve continuous production of highly concentrated and pure C2 chemicals through the electrochemical CO2 reduction reaction (eCO2RR) for artificial carbon cycling, yet it has remained unattainable until now. Despite one-pot tandem catalysis (dividing eCO2RR into two catalytical reactions CO C2) offering potential significantly enhancing efficiency, its mechanism remains unclear performance unsatisfactory. Herein, we selected different CO2-to-CO catalysts CO-to-acetate construct several catalytic systems acetic acid. Among them, a system comprising covalent organic framework (PcNi-DMTP) metal–organic (MAF-2) as catalysts, respectively, exhibited faradaic efficiency 51.2% with current density 410 mA cm–2 an ultrahigh acetate yield rate 2.72 mmol m–2 s–1 under neutral conditions. After electrolysis 200 h, 1 working electrode can continuously produce 20 mM acid aqueous solution relative purity 95+%. Comprehensive studies revealed that influenced not only by supply–demand relationship electron competition between processes in but also CO-to-C2 catalyst diluted
