摘要

以植物提取物龙葵为原料,通过绿色合成和共沉淀法合成了ZnO/CuTiO2/PVDF纳米复合材料。这种新型材料通过加入ZnO/CuTiO2纳米粒子作为电阻转导层,克服了PVDF(聚偏氟乙烯)固有的疏水性,从而提高了其光学和光催化活性。采用SEM、TEM、EDX、PL和UV-DRS对ZnOCuTiO2/PVDF纳米复合材料进行了表征。通过TEM和EDAX分析,确定了ZnO/CuTiO2/PVDF纳米复合材料的球形形貌和元素组成。ZnOCuTiO2/PVDF纳米复合材料的带隙为2.3 eV,比纯ZnO的带隙(3.2 eV)要低。利用太阳光照下台盼蓝(TB)的降解分析了样品的光催化活性。其中,ZnO/CuTiO2/PVDF纳米复合材料在45 min内的降解效率为95%,而ZnO的降解效率为61%。由于复合材料的带隙小,载流子复合率低,降解效率高于ZnO。此外,在活动减少后可重复使用多个周期,使其成为工业应用的重要资源。最后,采用圆盘扩散法研究样品对大肠杆菌和金黄色葡萄球菌的抑菌活性。因此,ZnO/CuTiO2/PVDF纳米复合材料具有更好的光催化和抗菌活性。

Green synthesis of ZnO/CuTiO2/PVDF nanocomposite using Solanum nigrum extract: photocatalytic and biological applications
A ZnO/CuTiO2/PVDF nanocomposite was synthesized via green synthesis using plant extract Solanum nigrum and co-precipitation. This novel material overcomes the inherent hydrophobicity of PVDF (polyvinylidene fluoride) by incorporating ZnO/CuTiO2 nanoparticles as resistive transduction layers, thereby facilitating its optical and photocatalytic activity. The ZnOCuTiO2/PVDF nanocomposite were characterized by SEM, TEM, EDX, PL and UV-DRS. According to the TEM and EDAX results spherical morphology and elemental composition of the ZnO/CuTiO2/PVDF nanocomposite were confirmed. The band gap of the ZnOCuTiO2/PVDF nanocomposite was determined to be 2.3 eV, which was comparatively lower than pure ZnO (3.2 eV) band gap. The photocatalytic activity of the samples is analyzed using degradation of Trypan Blue (TB) under sun light irradiation. Among the samples, ZnO/CuTiO2/PVDF nanocomposite exhibited 95 % degradation efficiency with 45 min over 61 % degradation efficiency of ZnO. Owing to low bandgap and lower charge-carrier recombination of composite the degradation efficiency was higher than ZnO. Additionally, the reused for up to multiple cycle after a negligible reduction in activity making it an important resource for industrial applications. Finally, the antibacterial activity of the samples is studied by disc diffusion method against E.Coli and S. aureus bacteria. Thus, ZnO/CuTiO2/PVDF nanocomposite with improved photocatalytic and antibacterial activity.
