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.

3D assembled carbon materials, featuring unique hierarchical porosity and interconnected channels, are essential for the advancement of emerging zinc-air batteries (ZABs). In this study, nitrogen (N) sulfur (S) co-doped nanoholes (N/S-CNHs) synthesized through a straightforward procedure involving self-assembly followed by carbonization. This process utilizes hybrid self-assembled covalent triazine framework sodium lignosulphonate (CTF@LS) as multifunctional precursor. The resulting N/S-CNHs exhibit distinctive microstructure composed interwoven nanoclusters, which facilitates efficient ion electron transport during electrocatalytic process. incorporation N S atoms intriguingly alters wetting properties catalyst microenvironment, thereby significantly facilitating transfer key intermediates their interaction with electrolyte. Consequently, optimized N/S-CNH-900 demonstrates remarkable activity ORR (E

As one of the most promising means to repair diseased tissues, stem cell therapy with immense potential differentiate into mature specialized cells has been rapidly developed. However, clinical application stem-cell-dominated regenerative medicine was heavily hindered by loss pluripotency during long-term in vitro expansion. Here, a composite three-dimensional (3D) graphene-based biomaterial, denoted as GO-Por-CMP@CaP, hierarchical pore structure (micro- macropore), developed guide directional differentiation human umbilical cord MSCs (hucMSCs) osteoblasts. GO-Por-CMP@CaP could act high-efficiency living material without "dead space", effectively regulating cellular response. The 3D topological generated via two-step modification on two-dimensional graphene mimic natural microenvironment cells, enhancing attachment, which is not only conducive for proliferation but also beneficial osteogenic differentiation. Meanwhile, wide existence interconnected macropores favorable bone ingrowth, capillary formation, well nutrients transportation. Furthermore, concurrent micro- and mesopores significantly promoted extracellular matrix (ECM) adsorption, ensured leading multiscale osteointegration. Both vivo assay demonstrated above three factors collaborated mutually nanosized calcium phosphate (CaP, chemical similarities inorganic components bone), provided abundant adhesive sites adequately induce absence any soluble growth factors. Proteomic analysis experiments confirmed that hucMSCs osteoblasts affecting PI3K-Akt signaling pathway through up-regulation SPP1 protein. Our study offers pure material-based behavior engineering dimension porosity material, provides insights design development substitutes materials.

Abstract Porous organic polymers (POPs) are emerging as up‐and‐coming photocatalysts for energy conversion, and environmental treatment. However, attention to simultaneously improving photoinduced charge separation, transfer, interfacial reaction is markedly lagged. Herein, the strategy of coupling ionic polarization, electron sponge effect enhancing built‐in electric field (BIEF), surface mass transfer process POPs proposed, which can be realized by a one‐pot post‐pyridiniumnation, Friedel‐Craft reaction. This method endows polarization elevating BIEF boosting separation/migration. The pyridiniumnation not only induces allow shallow trap free electrons but also effectively reduces oxygen adsorption energy, pertinent intermediates, thus leading stronger in 2.73‐fold neutral polymer strengthened O 2 activation. Additionally, photothermal performance with up 15 °C increment contributes enhancement photocatalysis. Consequently, iBPyP‐33 exhibits an unprecedentedly efficient photodegradation 100 ppm bisphenol A (BPA) just 20 min, photosynthesis H rate 3070 µmol g −1 h air, 6583 aided sodium ethylenediaminetetraacetic acid. study provides fresh, valuable insights into design high efficiency.
