Abstract Generally, the low electron–hole separation efficiency of covalent organic frameworks (COFs) prevents their catalytic performance from reaching satisfactory results. For this reason, creation heterojunctions is considered an effective strategy but usually suffers dimensional mismatch integrated material, even at expense its redox capacity. To overcome these difficulties, a novel 2D/2D S‐scheme heterojunction between H 2 N–Cu–MOF (NCM) and TpPa–1–COF (TP1C) successfully constructed for efficient photocatalytic production. The matching dimensions two crystalline porous materials enables with abundant surface reactive sites, strong interaction optimized electronic structure. Moreover, combination can also form S–scheme heterojunction, which not only promote pair, preserve ability, thus remarkably boosting competence. Consequently, rate optimal 20% NCM/TP1C in production reaches 4.19 mmol g −1 h , 46.5 times higher than that bare NCM, 22.1 folds over pure TP1C. This research offers innovative perspective formation based on crystal solar energy utilization.

Hydrogen Bonds and In situ Photoinduced Metallic Bi⁰/Ni⁰ Accelerating Z‐Scheme Charge Transfer of BiOBr@NiFe‐LDH for Highly Efficient Photocatalysis

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(41)

Опубликована: Июль 8, 2024

For heterojunction system, the lack of stable interfacial driving force and definite charge transfer channel makes separation efficiency unsatisfactory. The photoreaction mechanism occurring at interface also receives less attention. Herein, a 2D/2D Z-scheme junction BiOBr@NiFe-LDH with large-area contact featured by short hydrogen bonds strong electric field (IEF) is synthesized, in situ photoinduced metallic species assisting demonstrated. between O atoms from BiOBr H NiFe-LDH induce significant redistribution, establishing robust IEF. Notably, during photocatalytic reaction, Bi

Enhanced Charge Transfer Process and Photocatalytic Activity over a Phosphonate‐based MOF via Amorphization Strategy

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(15)

Опубликована: Фев. 16, 2024

Recently, amorphous materials have gained great attention as an emerging kind of functional material, and their characteristics such isotropy, absence grain boundaries, abundant defects are very likely to outrun the disadvantages crystalline counterparts, low conductivity, ultimately lead improved charge transfer efficiency. Herein, we investigated effect amorphization on process photocatalytic performance with a phosphonate-based metal-organic framework (FePPA) research object. Comprehensive experimental results suggest that compared FePPA, FePPA has more distorted metal nodes, which affects electron distribution consequently improves photogenerated separation Meanwhile, nodes in also greatly promote adsorption activation O
