Conjugated Microporous Polymers for Catalytic CO₂ Conversion

Advanced Science, Год журнала: 2024, Номер 11(14)

Опубликована: Фев. 7, 2024

Abstract Rising carbon dioxide (CO 2 ) levels in the atmosphere are recognized as a threat to atmospheric stability and life. Although this greenhouse gas is being produced on large scale, there solutions reduction indeed utilization of gas. Many these involve costly or unstable technologies, such air‐sensitive metal–organic frameworks (MOFs) for CO capture “non‐green” systems amine scrubbing. Conjugated microporous polymers (CMPs) represent simpler, cheaper, greener solution utilization. They often easy synthesize at scale (a one pot reaction many cases), chemically thermally stable (especially comparison with their MOF covalent organic framework (COF) counterparts, owing amorphous nature), and, result, cheap manufacture. Furthermore, surface areas, tunable porous chemical structures mean they reported highly efficient motifs. In addition, provide dual pathway utilize captured via conversion electrochemical into industrially valuable products. Recent studies show that all attractive properties can be realized metal‐free CMPs, presenting truly green option. The promising results two fields CMP applications reviewed explored here.

Abstract Photocatalytic oxygen (O 2 ) reduction to hydrogen peroxide (H O is considered be a promising method for energy storage. However, it suffers from the rapid recombination of carriers, limited solubility and slow diffusion , self‐decomposition H in traditional diphase systems. Here, self‐floating carbon dots/conjugated microporous polymer (CDs/CMP) photocatalytic system established production organic synthesis. Due D–π–A structure, porous hydrophobicity, CMP induced intramolecular charge transfer, exposed abundant reaction sites, enhanced adsorption. CDs act as “bridges” electron transmission regulate surface hydrophobicity CMP, further improving transfer optimizing interface. CDs/CMP exhibits high 8542.6 µmol g −1 h concurrent furoic acid at 2.22 m . This rate ≈90% higher than that system, exceeding all previously reported photocatalysts triphase Notably, achieves relative separation suppressing generated self‐decomposition. Theoretical calculations situ characterizations reveal mechanism evolution. provides insights into exploring application metal‐free heterogeneous reactions.
