Abstract

In this study, zinc sulfide (ZnS) nanoparticles were synthesized via a gas-liquid sulfidation process and incorporated into cellulose acetate (CA) nanofibers through electrospinning to fabricate composite photocatalytic materials for the degradation of methylene blue (MB) in water. The nanoparticles and resulting nanofibers were characterized to confirm their structural, morphological, and chemical properties. The ZnS/CA nanofibers exhibited high photocatalytic activity under ultraviolet (UV) irradiation and retained their activity over multiple degradation cycles. Toxicity assays using fibroblast cells demonstrated that the composite nanofibers did not induce toxic effects, highlighting their potential for environmentally safe water treatment applications.

电纺丝硫化锌/醋酸纤维素纳米纤维复合材料对亚甲基蓝降解的光催化活性和可重复利用性增强

本研究采用气液硫化法制备了硫化锌纳米粒子，并通过静电纺丝将其掺入醋酸纤维素纳米纤维中，制备了降解水中亚甲基蓝（MB）的复合光催化材料。对纳米颗粒和纳米纤维进行了表征，以确定其结构、形态和化学性质。ZnS/CA纳米纤维在紫外线照射下表现出较高的光催化活性，并在多次降解循环中保持其活性。利用成纤维细胞进行的毒性试验表明，复合纳米纤维不会引起毒性作用，突出了它们在环境安全水处理应用中的潜力。

期刊介绍： Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
