Molecular electrostatic potential (MESP) analysis revealed enhanced charge redistribution and increased electronegativity with La<sub>2</sub>O<sub>3</sub> incorporation, indicating improved chemical reactivity and potential in energy storage systems. X-ray diffraction (XRD) confirmed a transition from amorphous to semi-crystalline structures, maximized at 4 wt.% La<sub>2</sub>O<sub>3</sub>, while FT-IR spectra displayed characteristic peak shifts and bond formations evidencing strong RPET-La<sub>2</sub>O<sub>3</sub> interactions. Optical studies revealed a marked increase in the UV-region absorption coefficient (α) with increasing La<sub>2</sub>O<sub>3</sub> content, indicating enhanced photon-polymer interactions, while maintaining high transparency in the visible region. The direct optical band gap decreased from 3.98 eV (pristine RPET) to 3.77 eV at 8 wt.% loading, confirming matrix-filler interaction and tunability of optical properties. Dielectric analysis showed significant improvements in dielectric constant (ε′), dielectric loss (ε″), and AC conductivity (σ<sub>AC</sub>), with the 4 wt.% composite exhibiting the highest σ<sub>AC</sub> (1.12 × 10<sup>–5</sup> S·cm<sup>−1</sup> at 100 °C) and stable dielectric performance over a broad frequency range.

In this work, we designed and synthesized a novel series of g-C<sub>3</sub>N<sub>4</sub>/CoAl-LDH hybrid nanostructures through a simple hydrothermal process. Their crystallographic framework, surface morphology, elemental distribution, and porosity were systematically examined using XRD, SEM, XPS, and N₂ adsorption–desorption techniques. The cooperative effect between Co<sup>2+</sup> redox-active centers and the hydroxyl-enriched layered double hydroxide surface significantly accelerates hydrogen evolution kinetics, while the tailored band alignment broadens absorption in the visible-light region. Owing to these advantages, the optimized g-C<sub>3</sub>N<sub>4</sub>/CoAl-LDH catalyst delivered an outstanding hydrogen production rate of approximately 3033 μmol g<sup>−1</sup> h<sup>−1</sup> under visible-light irradiation, which is more than 7 times higher than that of bare CoAl-LDH (~ 430 μmol g<sup>−1</sup> h<sup>−1</sup>). Transient photocurrent measurements further confirmed rapid and stable photo-induced charge transport, highlighting efficient carrier separation under illumination. Moreover, the composite exhibited excellent long-term durability and recyclability, underscoring its strong potential for future applications in photocatalytic hydrogen evolution and wastewater remediation.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 27","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
