Low-cost and environmentally friendly nanomaterials fabricated using sol-gel, electrospinning, hydrothermal and solvothermal methods are highly important for the removal of dyes (which are important water pollutants) from water sources and for reducing biological activity on the membrane surface of treatment facilities. In this study, boron nitride/titanium dioxide composite nanofibers (BTFs) were synthesized using an electrospinning method. The structural and optical properties of the BTFs were investigated using various analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible spectroscopy (UV-vis) and Fourier transform infrared spectroscopy (FTIR), and then, their capability for photocatalytic dye removal and antibacterial activity was studied. SEM analysis of the characterized BTF nanofibers showed that the fiber structures were random, distant from each other and formed networks. Furthermore, the band energy calculated from the UV-vis spectrum was 2.81 eV. Subsequently, the catalytic activity for the removal of methylene blue and rhodamine B dyes from water was determined to be 83.7% and 84.3%, respectively. In addition, the BTF nanofibers exhibited a high antibacterial effect against , , and bacteria. In addition, antibacterial tests revealed that the bacterial culture containing BTF nanofibers showed a lethal effect even at low concentrations. Thus, BTF nanofibers are envisaged to play important roles in water purification and microorganism-control applications owing to their advantages of environmental friendliness, low-cost, and sustainability.
采用溶胶 - 凝胶法、静电纺丝法、水热法和溶剂热法制备的低成本且环保的纳米材料，对于从水源中去除染料（重要的水污染物）以及降低处理设施膜表面的生物活性极为重要。在本研究中，使用静电纺丝法合成了氮化硼/二氧化钛复合纳米纤维（BTFs）。利用多种分析技术，包括X射线衍射（XRD）、扫描电子显微镜（SEM）、紫外 - 可见光谱（UV - vis）和傅里叶变换红外光谱（FTIR），研究了BTFs的结构和光学性质，然后研究了它们光催化去除染料的能力和抗菌活性。对表征后的BTF纳米纤维进行的SEM分析表明，纤维结构随机，相互间距大且形成网络。此外，由紫外 - 可见光谱计算出的带隙能量为2.81 eV。随后，测定其从水中去除亚甲基蓝和罗丹明B染料的催化活性分别为83.7%和84.3%。此外，BTF纳米纤维对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌和铜绿假单胞菌表现出高抗菌效果。此外，抗菌测试表明，含有BTF纳米纤维的细菌培养物即使在低浓度下也显示出致死作用。因此，鉴于BTF纳米纤维具有环境友好、低成本和可持续性的优点，预计它们在水净化和微生物控制应用中发挥重要作用。
