摘要

纳米粒子具有大表面积和高反应活性等优越性能,可以替代传统肥料,提高养分吸收率。此外,考虑到化学和物理合成方法需要消耗大量能源并造成环境污染,植物介导的纳米粒子绿色合成因其提供了生态友好、生物兼容和成本低廉的解决方案而备受关注。本研究利用月桂叶进行了植物介导的氧化铁(Fe2O3)、氧化锌(ZnO)和二氧化钛(TiO2)纳米粒子的绿色合成,并通过紫外可见光谱、动态光散射(DLS)、傅立叶变换红外(FTIR)、X 射线衍射(XRD)和透射电子显微镜(TEM)对其结构特性进行了表征。紫外光谱和傅立叶变换红外分析显示出特征峰,表明存在所需的纳米粒子,而 DLS 分析和 TEM 图像则证实合成的粒子为纳米级。通过研究纳米颗粒在水培系统中对向日葵生长的影响,评估了其作为生物肥料在农业方面的应用潜力。应用了纳米粒子的植物组织的 TEM 图像证明了纳米粒子从根部到叶片的吸收和转移。此外,在向日葵上施用 5ppm 以下的 Fe2O3、ZnO 和 TiO2 NP 普遍提高了生理生长参数,如根长、鲜重和叶表面积,而施用 20ppm 的 Fe2O3 和 ZnO NP 则会导致生理生长参数显著下降。

Green synthesis and characterization of Fe2O3, ZnO and TiO2 nanoparticles and searching for their potential use as biofertilizer on sunflower

Nanoparticles, thanks to their superior properties such as large surface area and high reactivity, can be an alternative to traditional fertilizers for improving nutrient uptake. Furthermore, considering that chemical and physical synthesis methods require high energy consumption and cause environmental pollution, plant-mediated green synthesis of NPs has attracted great attention since it provides eco-friendly, biocompatible, and inexpensive solutions. In this present study, plant mediated green synthesis of Iron Oxide (Fe2O3), Zinc Oxide (ZnO) and Titanium Dioxide (TiO2) nanoparticles by using Laurus nobilis leaves (bay leaves) were carried out and their structural properties were characterized by UV visible spectra, Dynamic Light Scattering (DLS), Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM). UV spectrum and FTIR analysis exhibited characteristic peaks indicating the presence of the desired NPs, while DLS analysis and TEM images confirmed that synthesized particles are in nano-scale. The potential of nanoparticles as biofertilizer in agricultural uses were assessed by investigating their effects on sunflower growth in hydroponic system. TEM images of the NP applied plant tissues proved the uptake and translocation of NPs from root to leaf. Furthermore, Fe2O3, ZnO and TiO2 NP applications on sunflower up to 5 ppm generally improved physiological growth parameters such as root length, fresh weight and leaf surface area while 20 ppm of Fe2O3 and ZnO NPs application cause a significant decrease.
