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.

Опубликована: Июль 6, 2024

Abstract Since 2020, covalent organic frameworks (COFs) are emerging as robust catalysts for the photosynthesis of hydrogen peroxide (H 2 O ), benefiting from their distinct advantages. However, current efficiency H production and solar‐to‐chemical energy conversion (SCC) remain suboptimal due to various constraints in reaction mechanism. Therefore, there is an imperative propose improvement strategies accelerate development this system. This comprehensive review delineates recent advances, challenges, utilizing COFs photocatalytic production. It explores fundamentals challenges (e.g., oxygen (O ) mass transfer rate, adsorption capacity, response sunlight, electron‐hole separation efficiency, charge selectivity, desorption) associated with process, well advantages, applications, classification, preparation purpose. Various enhance performance highlighted. The aims stimulate further advancements discusses potential prospects, application areas field.

Опубликована: Янв. 1, 2025

Heterogeneous catalysis at the metal surface generally involves transport of molecules through interfacial water layer to access surface, which is a rate-determining step nanoscale. In this study, taking oxygen reduction reaction on electrode in aqueous solution as an example, using accurate molecular dynamic simulations, we propose novel long-range regulation strategy midinfrared stimulation (MIRS) with frequency approximately 1,000 cm-1 applied nonthermally induce structural transition from ordered disordered state, facilitating surfaces room temperature and increasing activity 50-fold. Impressively, theoretical prediction confirmed by experimental observation significant discharge voltage increase zinc-air batteries under MIRS. This MIRS approach can be seamlessly integrated into existing strategies, offering new for accelerating heterogeneous reactions gas sensing within system.

Abstract Fe single‐atom on N‐doped carbon (FeN‐C) catalysts emerge as promising alternatives to commercial Pt/C for the oxygen reduction reaction. Heterogeneous atom doping is proposed be effective modulating catalyst performance. Despite this, relationship between fine coordination structure of doped atoms and catalytic activity central metal site remains poorly understood. Herein, with S in either first shell (FeSN–C) or second (FeN–SC) active are synthesized compare effects different structure. FeN–SC exhibits prominent performance a half‐wave potential 0.92 V rotating disk electrode peak power density 251 mW cm −2 zinc–air battery. Theoretical studies reveal that effectively modulates electronic charge transfer at center. Compared directly coordinated within shell, located more optimizing adsorption desorption energy barriers oxygen‐containing intermediates sites. This study provides new strategy adjust by engineering multilayer center catalyst.
