Published: Feb. 5, 2025

Abstract Achieving synergistic oxidation and reduction represents a significant challenge in the field of photocatalysis. In this study, hydrothermal/in situ construction Bi atom clusters within 2 Sn O 7 /ZnIn S 4 (BSO/ZIS) heterostructures is reported. These exhibit self‐accelerating charge‐transfer mechanisms facilitated by internal electric fields bonding bridges, resulting highly efficient light absorption capabilities. X‐ray photoelectron spectroscopy (XPS) Kelvin probe force microscopy (KPFM), as well theoretical calculations, indicate that canonical induction promotion electrons holes lowers activation energy CHO* generation, allowing simultaneous CO toluene over catalyst, enhances proton‐coupling electron‐transfer processes, unique reaction mechanism. The reactant, Bi‐Bi (B‐BSO/ZIS) heterostructure achieves rate to 726.3 µmol g −1 h (99.9% selectivity) benzaldehyde 2362.0 (98.0% selectivity), which increases activity 14.6 5.7 times compared pristine ZnIn . This study underscores significance modulating photocatalytic pathway through strategic selection metal reactants, contributing rational design photocatalysts for enhanced adsorption stabilization *H.

Efficient Charge and Proton Balance Enabled by a 2D/2D S‐Scheme Heterojunction with a Nanochamber Design for Better Synergy of Photocatalytic CO₂ Methanation and Benzylamine Oxidation

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 6, 2024

Abstract Light‐driven CO 2 reduction integrated with benzylamine (BA) oxidation provides a promising means for achieving sustainable development, whereas whose effectiveness is challenged by imbalanced charge transfer/utilization and proton supply/consumption. To conquer these issues, herein, 2D/2D inorganic/organic S‐scheme heterojunction reported nanochamber design, featuring large‐area interfacial contact between the components carrier transfers sufficient exposure of spatially separated redox sites surface reactions. Remarkably, designed BiOI@hollow zinc‐porphyrin conjugated polymer (ZnPCP) catalyst delivers high CH 4 yield 577.1 µmol g cat −1 h stoichiometric N‐benzylidenebenzylamine (BDA) output 2300.3 , both selectivities exceeding 96%. Zn coordination to porphyrin not only amplifies internal electric field induces an intramolecular polarization within ZnPCP, but also facilitates adsorption/activation lowers energy barriers methanation, improving transfer/separation dynamics regulating reaction kinetics. Moreover, hollow chambers increase photon utilization, coordinate release consumption, encouraging dehydrogenation C─N coupling BA BDA, while simultaneously discouraging hydrogenation BDA secondary amines. This study emphasizes significance attaining equilibrium, providing fresh avenue enhancing efficiency photoredox catalysis.
