Crafting semiconducting heterojunctions represents an effective route to enhance photocatalysis by improving interfacial charge separation and transport. However, lattice mismatch (δ) between different semiconductors can significantly hinder dynamics. Here, meticulous tailoring is reported create a covalent heterointerface with built-in electric field (BIEF), imparting markedly improved hydrogen peroxide (H

Abstract The oxidative degradation of plastics in conjunction with the production clean hydrogen (H 2 ) represents a significant challenge. Herein, Ni 3 S 4 /ZnCdS heterojunction is rationally synthesized and employed for efficient H high‐selectivity value‐added chemicals from waste plastic. By integrating spectroscopic analysis techniques density functional theory (DFT) calculations, solely electron transfer‐mediated reaction mechanism confirmed, wherein extracts electrons ZnCdS (ZCS) to promote spatial segregation photogenerated holes, which not only facilitates but also maintains high oxidation potential holes on ZCS surface, favoring hole‐dominated plastic oxidation. Notably, catalyst exhibited rates as 27.9 17.4 mmol g −1 h , along selectivity 94.2% 78.3% liquid product toward pyruvate acetate polylactic acid (PLA) polyethylene terephthalate (PET), respectively. Additionally, carbon yields 26.5% 2.2% are measured after 9 photoreforming, representing highest values reported date. Overall, this research presents promising approach converting into fuel valuable chemical products, offering solution growing issue “ White Pollution ”.

Abstract The interlayer stacking modes of 2D covalent‐organic frameworks (COFs) directly influence their structural features, ultimately determining functional output. However, controllably modulating the structure in traditional metal‐free COFs, based on same building blocks, remains challenging. Here, two trinuclear copper organic are synthesized successfully with different structures: eclipsed AA Cu 3 ‐PA‐COF‐AA and staggered ABC ‐PA‐COF‐ABC, using monomers. Remarkably, various functionalities, including porosity electronic optical properties, can be effectively regulated by stacking. As a result, ‐PA‐COF‐ABC exhibit significantly activities toward photoreduction U(VI), presenting promising strategy for removing radioactive uranium pollution. Due to its broader visible‐light absorption range superior photogenerated carrier migration separation efficiency, achieves U(VI) removal ratio 93.6% without additional sacrificial agents an air atmosphere—≈2.2 times higher than that (42.0%). To best knowledge, this is first study elucidate effect COFs photocatalytic activity reduction. This finding may inspire further exploration structure‐function relationship as photocatalysts potential photoinduced radionuclides.

Abstract Modulating the molecular structure to achieve full reaction including oxygen reduction and water oxidation is a promising strategy for efficient photosynthesis of hydrogen peroxide (H 2 O ) but remains challenge. Herein, triphenylamine naphthalimide‐based conjugated porous polymers are synthesized with photo oxidation‐reduction structures, then sulfonate (─SO 3 H) quaternary ammonium groups introduced via post‐modification produce two photocatalysts named NI‐TPA‐NI‐SO H NI‐TPA‐NI‐N, respectively. Introducing charged functional has improved hydrophilicity (O adsorption, beyond that, ─SO further stabilizes adsorbed bonding as well accelerates photogenerated carrier separation electron/proton transport that enables . Therefore, motivated by charge separation, stabilized boosted proton‐coupled electron transfer, exhibits highest light‐driven production rate among three photocatalysts, reaching 3.40 mmol g −1 h , which 4.9‐fold NI‐TPA‐NI. Remarkably, in presence ethylenediaminetetraacetic acid disodium salt, its significantly enhances 14.5 superior most reported organic best knowledge.
