All-weather highly efficient degradation of persistent organic pollutants over RhB-sensitized BiOCl under natural sunlight

Journal of Environmental Chemical Engineering 2025年第4期13卷

作者： Wen Sun Chunping Su Wei Zhang Hui Li Huiping Zhao Rong Chen State Key Laboratory of New Textile Materials and Advanced Processing Wuhan Textile University Wuhan 430200 PR China Engineering Research Center for Clean Production of Textile Printing and Dyeing Ministry of Education Wuhan Textile University Wuhan 430200 PR China School of Chemistry and Environmental Engineering Wuhan Institute of Technology Donghu New & High Technology Development Zone Wuhan 430205 PR China

Persistent organic pollutants (POPs) pose significant environmental and health risks due to their stability, toxicity, and propensity for bioaccumulation. Traditional treatment methods often fall short in effectively degrading these pollutants, facing challenges such as high costs, low efficiency, and particularly inadequate mineralization rates. In this study, we employ Rhodamine B (RhB) to sensitize BiOCl, thereby significantly broadening its spectral absorption range. The RhB-sensitized BiOCl demonstrates remarkable photocatalytic activity under both visible light and natural sunlight, achieving rapid degradation and high mineralization of Bisphenol A (BPA). BPA degradation experiments were conducted under natural light across various seasons (from March to October), at different times of the day (from sunrise to sunset), and under diverse weather conditions (sunny, cloudy and rainy). The results confirmed the significant capability and universality of RhB-sensitized BiOCl in rapidly degrading BPA at varying concentrations under natural light conditions. The primary reactive oxygen species (ROS) involved in BPA degradation along with potential degradation pathways were identified under both visible light and real sunlight. Additionally, RhB-sensitized BiOCl exhibits high degradation efficiency for other POPs such as phenol, 4-chlorophenol, and 2,4-dichlorophenol, thus showcasing broad applicability in treating wastewater contaminated with POPs. This study indicates that dye-sensitized BiOCl offers a viable, sustainable, and efficient solution for the remediation of POPs under natural light conditions.

Transient surface microdissolution properties of meta-aramid fiber

Surfaces and Interfaces 2025年 70卷

Meta-aramid possesses good stability and excellent mechanical properties. However, their lack of reactive chemical groups results in low surface activity, limiting the ability to construct structural composites. The method provided in this paper utilizes the rapid volatilization of DMAc under high-temperature conditions to microsolvate the surface of meta-aramid fibers, efficiently achieving surface modification of meta-aramid. The effects of various processing conditions on the molecular aggregate structure, surface microstructure, and fabric mechanical properties of the modified meta-aramid were systematically studied to determine the optimal process for surface microdissolution via the transient high-temperature method and to construct a relevant mechanistic model. The results indicate that the DMAc/LiCl system can achieve superior microdissolution on the surface of meta-aramid in only 4 s at 175 °C, with a minimal effect on its mechanical properties. Transient modulation of the meta-aramid surface structure using the DMAc/LiCl system provides a new approach for the efficient preparation of meta-aramid structural composites. © 2025 Elsevier B.V.

Synergistic triple-site engineering in ABX 3 -type hybrid halides for high-performance nonlinear optical crystals

Chinese Chemical Letters 2025年

作者： Yuwei Kang Can Yang Jun Zhang Qi Wu State Key Laboratory of New Textile Materials and Advanced Processing Technologies Wuhan Textile University Wuhan 430200 China State Key Laboratory of Functional Crystals and Devices Fujian Institute of Research on the Structure of Matter Chinese Academy of Sciences Fuzhou 350108 China Key Laboratory of Functional Molecule Design and Interface Process Anhui Jianzhu University Hefei 230601 China

Achieving non-centrosymmetric (NCS) configurations in ABX 3 -type hybrid halides remains a critical challenge for nonlinear optical (NLO) aterials due to the conflicting requirements of high second-harmonic generation (SHG) response, wide bandgap, and phase-matching capabilities. Herein, we propose a triple-site modulation strategy by synergistically tailoring the A -site cations (2-methylimidazole cation/1-ethyl-3-methylimidazole cation), B -site metals (Sn 2+ /Pb 2+ ), and X -site halogens (Cl/Br), which effectively disrupts lattice symmetry and enables NCS crystallization. Our results demonstrate a strong SHG response, an expanded optical bandgap and increased birefringence. The optimized compound C 6 H 11 N 2 PbCl 3 exhibits a record SHG efficiency of 3.8 × KDP, a wide bandgap (3.87 eV), and enhanced birefringence (0.14), surpassing majority hybrid NLO materials. The innovative anionic framework introduced here broadens the scope of hybrid NLO crystals, facilitating the integration of various aromatic heterocyclic cations. This research provides a robust strategy for the development of advanced NLO materials.

Flexible strain sensors are critical to several potential intelligent applications, such as human-machine interfaces, soft robotics, human motion detection, and safety monitoring of components. Stretchable functional materials are important components of strain sensors, and they are still major challenges for high performance strain sensors. Herein, we demonstrate a novel strategy of designing and optimizing flexible strain sensor by developing topological structure modulated high permittivity elastic nanocomposite. The topological structure with three-phase percolative nano-nanonetworks produces synergistic effects of space charge enhancement and local electric field modulation, and it gives rise to an ultrahigh dielectric permittivity (113.4, at 1 kHz, over 1500% enhancement than that of commercial elastic polyurethane matrix) and excellent comprehensive electromechanical performance, and the optimal comprehensive electromechanical performance reaches to 542.91 MPa-1, which is over 9-fold than that of commercial polyurethane elastic film. An interdigital capacitive strain sensor is designed using the topological structured elastic dielectric nanocomposite. It possesses high initial capacitance density and positive capacitance response with stain, achieving high signal-to-noise ratio, high capacitance response sensitivity, and wide linear range, and it breaks through disadvantages of negative sensitivity and narrow linear range for conventional interdigital strain sensors. The prepared integrated strain sensor arrays are able to measure local strain of convoluted surfaces and monitor the motion of soft actuators in real time, and they would make conditions for intelligent control systems and the study of morphological intelligence.
