Abstract

In this study, polyvinyl alcohol (PVA)/g-C₃N₄/FeWO₄ nanofibres (PFG NFs) were synthesized via the electrospinning method, while bare materials were prepared using the hydrothermal method. These nanofibres were explored for their photocatalytic efficiency, antibacterial activity, and biocompatibility. The PFG NFs was characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) with elemental mapping, and energy-dispersive X-ray spectroscopy (EDS). The photocatalytic performance was evaluated through the degradation of Reactive Black 5 (RB5) dye under solar light irradiation, achieving approximately 90% degradation in 100 min. Additionally, the antibacterial efficacy was assessed against Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus), showing inhibition zones of 18 mm and 20 mm, respectively. Biocompatibility assessments using a zebrafish model revealed that the nanofibres exhibited good biocompatibility, with an applicable survival rate of 85%. These results indicate that the PFG NFs are promising candidates for environmental remediation, antibacterial applications, and biocompatibility-safe implementation.

电纺丝PVA/g-C3N4/FeWO4纳米纤维作为RB5染料降解、抗菌活性和斑马鱼胚胎生物相容性的多功能平台

本研究采用静电纺丝法合成聚乙烯醇(PVA)/g-C3N4/FeWO4纳米纤维（PFG NFs），采用水热法制备裸材料。研究了这些纳米纤维的光催化效率、抗菌活性和生物相容性。采用x射线衍射（XRD）、傅里叶变换红外光谱（FTIR）、元素映射场发射扫描电镜（FESEM）和能量色散x射线能谱（EDS）对PFG NFs进行了表征。通过在日光照射下降解活性黑5 （RB5）染料来评价其光催化性能，在100 min内降解约90%。此外，对大肠杆菌（E.coli）和金黄色葡萄球菌（S.aureus）的抑菌效果进行了评估，分别显示出18 mm和20 mm的抑制区。利用斑马鱼模型进行的生物相容性评估显示，纳米纤维具有良好的生物相容性，适用存活率为85%。这些结果表明，PFG纳米颗粒在环境修复、抗菌应用和生物相容性安全方面具有很好的应用前景。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
