Modulating In‐Plane Conjugation and Core Polarity in Naphthalimide‐Based Covalent Organic Frameworks Enables Efficient H2O2 Photosynthesis

open access: yesTransformative Chemistry, EarlyView.
In this work, we integrate photoactive naphthalimide unit into highly crystalline donor–acceptor covalent organic frameworks (D–A COFs) and achieve fine‐tuning of the electronic structure of D–A COFs by synergistically modulating the in‐plane conjugation and core polarity.

Beyond Removal Efficiency: Environmental Risk Assessment of Tartrazine Degradation via ZnO and TiO2 Nanoparticles in Mussels

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Tartrazine (TZ) is a widely used synthetic azo dye with high aqueous stability, resulting in persistence in wastewater. Photoreactive nanomaterials, principally zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs), are frequently employed for dye removal under light‐exposed conditions; nevertheless, their ecotoxicological ...

Immobilized CuCl2/TiO2 photocatalysts for the selective oxidation of benzyl alcohol to benzaldehyde

open access: yesPhotochemistry and Photobiology, EarlyView.
The photocatalytic aerobic oxidation of benzyl alcohol to benzaldehyde was investigated using free and alginate‐immobilized CuCl2 and/or TiO2 (P25) catalysts under UV irradiation. Immobilization enabled catalyst recovery and maintained high benzaldehyde selectivity but led to reduced activity due to internal oxygen diffusion limitations, which were ...

Beyond Water: Deep Eutectic Solvents Enable Dye‐Sensitised Photocatalytic Hydrogen Production

open access: yesChemSusChem, Volume 19, Issue 9, 14 May 2026.
Dye‐sensitised photocatalytic H2 evolution is demonstrated for the first time in deep eutectic solvents (DESs). Carbazole‐based dyes with different hydrophobicity sensitise Pt@TiO2, revealing that heterogeneous dye–DES combinations maximise activity. Interfacial solvation and charge transfer govern enhanced hydrogen production under visible light. This
