Abstract Converting carbon dioxide (CO 2 ) into fuel and high‐value‐added chemicals is considered a green effective way to solve global energy environmental problems. Covalent triazine frameworks (CTFs) are extensively utilized as an emerging catalyst for photo/electrocatalytic CO reduction reaction RR) recently recognized their distinctive qualities, including excellent thermal chemical stability, π‐conjugated structure, rich nitrogen content, strong affinity , etc. Nevertheless, single‐component CTFs have the problems of accelerated recombination photoexcited electron‐hole pairs restricted conductivity, which limit application RR. Therefore, emphasis will then summarize strategies enhancing photocatalytic electrocatalytic efficiency RR in this paper, atom doping, constructing heterojunction This review first illustrates synthesis advantages field Subsequently, mechanism CTF‐based materials described. Lastly, challenges future prospects addressed, offers fresh perspective development

Wood is easily affected by decay fungi, mildew insects, water, UV, and other factors when used outdoors. In particular, on the surface of wood negatively affects appearance practical use or wood-based engineered products. recent years, as a class popular crystalline materials, metal–organic frameworks (MOFs) have been widely applied in electrochemistry, adsorption, anti-mildew efforts, areas. this study, we first grew Co-based framework (Co-MOF) situ subsequently converted Co-MOF into cobalt–nickel double hydroxide layer, which formed micro- nanohierarchical composite structures surface. The low energy CoNi-DH@wood was further modified via impregnation with sodium laurate to obtain superhydrophobic (CoNi-DH-La@wood). We characterized microstructure, chemical composition, water contact angle, anti-mold properties CoNi-DH-La@wood using SEM, XRD, XPS, angle tests, anti-fungal tests. XPS results confirmed that coated surface, long-chain grafted onto it. had 151°, demonstrating excellent self-cleaning ability. addition, fabricated balsa exhibited environment stability. Lastly, 30-day test because coating successfully summary, work presents an attractive strategy for obtaining at room temperature, thereby endowing products properties.

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.

Covalent organic Frameworks (COFs) are a class of crystalline macromolecular materials build-up by monomers with specific symmetries or functionalities. There important limitations in the synthesis highly ordered COFs, such as shape and packing building blocks. Thus, presence fluorine atoms that lie perpendicular to bisecting plane BODIPY derivatives together four bulky methyl groups could hinder crystallization process COF synthesis. For reason, BODIPY-based COFs rarely incorporated networks. In this work, following mixed linker strategy, pre-synthetic method dope structures units was developed. The have been processed into fluorescent Organic Nanosheets (CONs) defined particle-size distributions around 100 nm, suitable for cellular biomedical applications. viability CONs evaluated using Sk-Mel-103 cells, demonstrating internalization showing 100% cell viability. We envisage work accelerate discovery new COF-based sciences.
