Environmental pollution is steadily rising and is having a negative influence on all living things, especially human beings. The advancement of nanoscience in recent decades has provided potential to address this issue. Functional metal oxide nanoparticles/nanofibers have been having a pull-on effect in the biological and environmental domains of nanobiotechnology. Current work, for the first time, is focusing on the electrospinning production of ZrSnTiO/SnO ceramic nanofibers that may be utilized to battle lethal infections swiftly and inexpensively. By using characterizations like XRD, FT-IR, FESEM, TEM, PL, and UV-Vis-DRS, the composition, structure, morphology, and optical absorption of samples were determined. The minimum inhibitory concentration (MIC) approach was used to investigate the antibacterial activity. Notably, this research indicated that nanofibers exert antibacterial action against both Gram-positive and Gram-negative bacteria with a MIC of 25 µg/mL. Furthermore, negatively charged was drawn to positively charged metal ions of ZrSnTiO/SnO, which showed a robust inhibitory effect against . It was interesting to discover that, compared to pure TiO, ZrSnTiO/SnO nanofibers revealed increased photocatalytic activity and exceptional cyclability to the photodegradation of Rhodamine B. The composite completely degrades dye in 30 min with 100% efficacy and excellent (97%) reusability. The synergetic effects of ZrSnTiO and SnO may be responsible for increased photocatalytic and bactericidal activity.
环境污染正在稳步上升，对所有生物，尤其是人类产生负面影响。近几十年来纳米科学的进步为解决这一问题提供了潜力。功能性金属氧化物纳米颗粒/纳米纤维在纳米生物技术的生物和环境领域一直具有吸引力。目前的工作首次聚焦于静电纺丝制备ZrSnTiO/SnO陶瓷纳米纤维，这种纳米纤维可用于快速且低成本地对抗致命感染。通过使用XRD、FT-IR、FESEM、TEM、PL和UV-Vis-DRS等表征手段，确定了样品的组成、结构、形态和光吸收。采用最低抑菌浓度（MIC）方法研究抗菌活性。值得注意的是，这项研究表明纳米纤维对革兰氏阳性菌和革兰氏阴性菌均具有抗菌作用，MIC为25µg/mL。此外，带负电荷的[此处原文缺失具体物质]被吸引到ZrSnTiO/SnO带正电荷的金属离子上，这对[此处原文缺失具体物质]表现出强大的抑制作用。有趣的是，与纯TiO相比，ZrSnTiO/SnO纳米纤维显示出更高的光催化活性以及对罗丹明B光降解的优异循环性。该复合材料在30分钟内以100%的效率完全降解染料，并且具有出色的（97%）可重复使用性。ZrSnTiO和SnO的协同效应可能是光催化和杀菌活性增强的原因。
