Abstract In this study, a new type of oxycarbide-based compounds, namely lanthanum titanium oxycarbide and neodymium oxycarbide, were synthesized through solid-state reaction to replace due its rapid charge carrier recombination limited responsiveness visible light in photocatalysis. The structural, morphological, optical absorption vibrational properties the catalysts thoroughly characterized using powder X-ray diffraction, scanning electron microscopy, ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy assess their suitability for catalytic applications. Subsequently, photocatalytic behaviour materials was evaluated ability degrade hazardous Congo red dye various types water, including deionized domestic utility water used household purposes, seawater, under illumination. Notably, exhibited superior degradation efficiencies dye, achieving maximum rates 87% 89%, respectively, routine purposes within duration 90 minutes, when compared TiOC. However, efficiency slightly lower seawater. Additionally, demonstrated promising hydrogen evolution activity, generating 19.7 21.1 µmol/g, 180 minutes. enhanced removal generation activity has been attributed synergistic effects improved absorption, higher exciton separation supportive pH environment presence lanthanum, carbon ions combined entity.

Functional Groups‐Regulated Organic Semiconductors for Efficient Artificial Photosynthesis of Hydrogen Peroxide

Advanced Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 18, 2025

Abstract Hydrogen peroxide (H 2 O ) is an environmentally friendly reagent, and organic semiconductors (OSCs) are ideal photocatalysts for the synthesis of H due to their well‐defined molecular structure, strong donor‐acceptor interactions, efficient charge separation. This review discusses regulatory mechanisms functional group modifications in tuning photocatalytic performance OSCs, highlighting relationship between structure catalytic performance. For example, electron‐regulating groups, such as cyano halogen, induce dipoles, facilitating migration photogenerated electrons. Fluorine groups optimize band prolong carrier lifetime high electronegativity. π‐Conjugated extension like anthraquinone thiophene, expand conjugation, improve visible light capture, stabilize intermediates through redox cycles. Hydroxyl enhance surface hydrophilicity promote activation, while imine bond protonation adjusts distribution improves selectivity cycle stability. Multi‐active site sulfonic acid amide, accelerate reaction kinetics inhibit decomposition. Functional absorption, separation, reactions electronic regulation, intermediate adsorption optimization, proton‐electron transfer. Future work should integrate machine learning identify optimal combinations develop green functionalization strategies photocatalyst synthesis.
