Abstract

The study explored the preparation of plant extract from Thuja occidentalis and the green synthesis of Ytterbium (Yb) doped ferrite nanoparticles, including MgFe₂O₄, CuFe₂O₄ and MgCuFe₂O₄. The plant extract was prepared by boiling fresh Thuja occidentalis leaves in distilled water and subsequently filtering the solution. The extract, abundant in phytochemicals such as flavonoids, tannins, and terpenoids, served as both a reducing and stabilizing agent in the precipitation-based synthesis of Yb doped ferrite nanoparticles. The molar ratios of the metals were maintained to achieve desired doping levels and NaOH was added to induce precipitation, which was then calcined to produce ferrite nanoparticles. The photocatalytic and antioxidant activities of the synthesized nanoparticles were evaluated using methylene blue (MB) dye degradation under visible light and DPPH radical scavenging assays, respectively. Characterization techniques, including XRD, FTIR, UV-Vis spectroscopy, XPS, SEM-EDS, TEM and VSM spectroscopy, confirmed the successful synthesis, structural integrity, functional and magnetic properties of the nanoparticles. The results revealed that Yb doped CuFe₂O₄ ferrites exhibited superior photocatalytic and antioxidant activities compared to the other ferrite nanoparticles, making them promising candidates for environmental and health-related applications.

本研究探索了西花植物提取物的制备及Yb掺杂铁氧体纳米粒子MgFe2O4、CuFe2O4和MgCuFe2O4的绿色合成。用蒸馏水将新鲜的西树叶煮沸，然后过滤得到植物提取物。该提取物富含黄酮类化合物、单宁和萜类化合物等植物化学物质，在沉淀法合成掺杂Yb的铁氧体纳米颗粒中充当还原剂和稳定剂。保持金属的摩尔比以达到所需的掺杂水平，并添加NaOH来诱导沉淀，然后煅烧生成铁酸盐纳米颗粒。利用可见光降解亚甲基蓝（MB）染料和清除DPPH自由基的实验，分别评价了合成的纳米颗粒的光催化活性和抗氧化活性。表征技术包括XRD、FTIR、UV-Vis光谱、XPS、SEM-EDS、TEM和VSM光谱，证实了纳米颗粒的成功合成、结构完整性、功能和磁性能。结果表明，与其他铁氧体纳米颗粒相比，Yb掺杂CuFe2O4铁氧体具有优越的光催化和抗氧化活性，使其成为环境和健康相关应用的有希望的候选材料。

期刊介绍： Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
