Abstract Covalent organic frameworks (COFs) are a promising class of polymers with the merits robust framework, ultrahigh porosity, and molecularly precise backbones, which reveals great potential for solar‐to‐chemical energy conversion in context mitigating environmental crises. However, photochemical activities individual COFs not as desired, primarily due to their limited light absorption, insufficient dissociation photogenerated excitons readily recombined carriers. Recently, COFs‐based metal‐free heterojunctions synergistic effects provide feasible route boost photocatalytic activity more environmentally friendly cost‐competitive manners. Herein, it is first systematically overview advances from heterojunction types, heterointerfaces interactions, primary design mechanisms. Then, typical photocatalysts (e.g., g‐C 3 N 4 ‐COFs, carbon materials‐COFs, polymer semiconductor‐COFs, COFs‐COFs heterojunction) summarized. Finally, challenges long‐term outlooks future offered terms efficiency, yield, stability, cost reaction mechanisms, well standardized evaluation method activities. It anticipated that this review can deliver new insights into fundamental engineering conversion, further accelerate development area.

Abstract Photocatalytic production of hydrogen peroxide (H 2 O ) represents a significant approach to achieving sustainable energy generation through solar energy, addressing both shortages and environmental pollution. Among various photocatalytic materials, covalent organic frameworks (COFs) have gained widespread attention in‐depth research due their unique advantages, including high porosity, predesignability, atomic‐level tunability. In recent years, progress has been made in the development, performance enhancement, mechanistic understanding COF‐based photocatalysts. This review focuses on latest advancements H using COFs, particularly emphasizing rational design COF structures regulate catalytic exploring fundamental processes involved photocatalysis. Based current achievements this field, paper also discusses existing challenges future opportunities, aiming provide reference for application COFs production.

Abstract The persistent threats posed by toxic chemical warfare agents (CWAs) such as mustard gas (bis(2‐chloroethyl) sulfide, HD) and bacterial contaminants demand the development of innovative, sustainable mitigation strategies. Photocatalytic processes that generate reactive oxygen species (ROS) offer a promising dual‐functional approach for both detoxification antibacterial defense. In this study, two structurally analogous covalent organic frameworks (COFs), BPY‐COF BD‐COF, are synthesized using benzotrithiophene donor unit paired with bipyridine biphenyl, respectively. These COFs exhibit high crystallinity, broad‐spectrum light absorption, efficient charge carrier transport, demonstrating superior performance due to incorporation heteroatoms. achieved ultrafast simulant 2‐chloroethyl ethyl sulfide (CEES) half‐life 35 min 100% selectivity sulfoxide (CEESO) under white LED light, outperforming BD‐COF. Additionally, electrospun composite fibers containing 40 wt.% maintained comparable CEES degradation rates exhibited over 99% efficiency against Escherichia coli Bacillus subtilis within 60 min. findings highlight potential multifunctional photocatalyst integrated applications in defense, addressing critical challenges public health safety.

Abstract Covalent organic frameworks (COFs) with stable crystalline porous structures and flexible assembly properties contribute to the direct photocatalytic synthesis of H 2 O meet growing global demand. To address challenges insufficient redox capacity photogenerated carrier recombination COFs, S‐scheme heterojunction is constructed from COFs quantum dots (QDs) improve production . Herein, 0D ZnCdS QDs (ZCS) uniformly anchor on surface a 2D conjugated tetrathiafulvalene‐based COF (TT‐COF), affording TT‐COF/ZCS. Formation effectively prevents agglomeration ZCS, modulates energy band structure TT‐COF, enhances migration carriers ability. As total consequence, optimized (TZ‐40) able afford in yield up 5171 µmol g −1 h under visible light irradiation , much higher than those for 2520 2647 The present result demonstrates great potential COFs/QDs‐based heterojunctions applications including production.
