A Crystalline Partially Fluorinated Triazine Covalent Organic Framework for Efficient Photosynthesis of Hydrogen Peroxide

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(19)

Published: March 1, 2022

A partially fluorinated, metal-free, imine-linked two-dimensional triazine covalent organic framework (TF50 -COF) photocatalyst was developed. Fluorine (F)-substituted and nonsubstituted units were integrated in equimolar amounts on the edge aromatic units, where they mediated two-electron O2 photoreduction. F-substitution created an abundance of Lewis acid sites, which regulated electronic distribution adjacent carbon atoms provided highly active sites for adsorption, widened visible-light-responsive range catalyst, while enhancing charge separation. Varying proportion F maximized interlayer interactions TF50 -COF, resulting improved crystallinity with faster carrier transfer robust photostability. The -COF catalyst demonstrates high selectivity stability photoreduction into H2 , a yield rate 1739 μmol h-1 g-1 remarkable apparent quantum efficiency 5.1 % at 400 nm, exceeding performance previously reported nonmetal COF-based photocatalysts.

Engineering Covalent Organic Frameworks as Heterogeneous Photocatalysts for Organic Transformations

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(47)

Published: Sept. 14, 2022

Abstract Covalent organic frameworks (COFs) are an emerging category of polymers with highly porous crystalline structures. In the last decade, reports on use COFs as heterogeneous photocatalysts for transformations have shown significant progress. Still, comprehensive reviews mechanisms photocatalytic using lacking. This Review provides a and systematic overview COF‐based transformations. Firstly, we discuss photophysical properties characterization methods photocatalysts. Then, general mechanism, advantages, strategies to improve efficiency summarized. After that, advanced examples analyzed regard underlying mechanisms. The ends critical perspective challenges prospects.

Construction of Core–Shell MOF@COF Hybrids with Controllable Morphology Adjustment of COF Shell as a Novel Platform for Photocatalytic Cascade Reactions

Advanced Science, Journal Year: 2021, Volume and Issue: 8(19)

Published: Aug. 10, 2021

Recently, novel core-shell MOF@COF hybrids display excellent performance in various fields because of their inherited advantages from parent MOFs and/or COFs. However, it is still a grand challenge to adjust the morphology COFs for consequent improvement. Herein, Ti-MOF@TpTt hybrid coated with ultra-thin COF nanobelt, which different fibrillar-like COF, successfully synthesized through sequential growth strategy. The as-obtained Pd decorated catalyst exhibits much higher photocatalytic than those Ti-MOF, TpTt-COF, and shell cascade reactions ammonia borane (AB) hydrolysis nitroarenes hydrogenation. These can be attributed its high BET surface area, structure, type II heterojunction, offers more accessible active sites improves separation efficiency photo-generated carriers. Finally, possible mechanisms reaction are also proposed well explain improved this system. This work presents constructive route designing controllable adjustment shell, leading ability broaden applications MOF/COF materials.
