Abstract Covalent organic frameworks (COFs) feature π‐conjugated structure, high porosity, structural regularity, large specific surface area, and good stability, being considered as ideal platform for photocatalytic application. Although single COFs have achieved significant progress in photocatalysis benefiting from their distinctive properties, the COFs‐based hybrids provide an extraordinary opportunity to achieve superior performance. From perspective of carrier transfer mechanism, a systematic summary based on other functional materials (metal atoms, metal clusters/nanoparticles, inorganic semiconductors, metal–organic frameworks, polymers) can offer valuable guidance design hybrids. In this review, mechanism hybrid (such Schottky junction, type II heterojunction, Z‐scheme S‐scheme heterojunction) is briefly introduced. Subsequently, performance water splitting, CO 2 reduction, pollutant degradation are comprehensively reviewed. Specifically, separation different types highlighted. Finally, challenges prospects envisaged. The insights presented review expected be helpful rational obtain outstanding activity. image

The urgency of reducing pollution and developing clean energy storage requires efficient photocatalytic hydrogen evolution (PHE) tactics. To improve solar conversion efficiency, it is highly imperative to accelerate the photocarriers separation transport through materials design. A stable photocatalyst based on TpPa-COFs (triformylphloroglucinol phenylenediamine covalent organic frameworks) was developed by a molecular-level design strategy. study successfully introduced molecular-scale Ir active site onto surface via coordination bonds. It verified structural integrity existence basic characterizations, such as Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron (XPS), transmission electron microscopy (TEM). After Ir-based compound joining, absorption edge TpPa-COF-M1 TpPa-COF-M2 extended 750 nm. TpPa-COF + M1 exhibited highest H2 rate 662 µmol/h (10 mg catalyst) under visible-light (λ ≥ 420 nm) irradiation. apparent quantum yield (AQY) calculated be 1.9%, 3.8%, 4.8%, 2.8%, 1.8%, 0.3% at monochromatic wavelengths 420, 450, 470, 500, 550, 600 nm, respectively. Our findings confirm that photocatalysts can effectively boost performance reduce cost in reactions provide an important strategy for designing photocatalysts.
