Abstract In the present study, we adopted, a green approach for the synthesis of ZnFe2O4 nanoparticles using the aqueous flower extract of Nyctanthes arbor-tristis. This extract served as the reducing agent for the synthesis of ZnFe2O4. The obtained nanoparticles were characterized by X-ray diffraction studies which indicated the formation of single phase ZnFe2O4. The size of the nanoparticles was in the range of 4.5–12 nm with calcination temperature as revealed from X-ray diffraction and Transmission electron microscopy, UV-Visible spectroscopy. Photocatalysis studies were made on RhodamineB dye, to assess the degradation capability of the nanopowders calcined at different temperature.

夜蛾花提取物生物合成铁酸锌 (ZnFe2O4) 纳米颗粒及其光催化活性

摘要 在本研究中，我们采用了一种使用 Nyctanthes arbor-tristis 的水花提取物合成 ZnFe2O4 纳米颗粒的绿色方法。该提取物用作合成 ZnFe2O4 的还原剂。获得的纳米颗粒通过 X 射线衍射研究表征，表明形成了单相 ZnFe2O4。从 X 射线衍射和透射电子显微镜、紫外-可见光谱显示，纳米颗粒的尺寸在 4.5-12 nm 范围内，煅烧温度为 4.5-12 nm。对罗丹明 B 染料进行了光催化研究，以评估在不同温度下煅烧的纳米粉末的降解能力。
