Abstract

The approach to the synthesis of cerium oxide nanoparticles (CeO2NPs) using plants as capping agents has been widely researched because of its eco-friendly, low-cost, simple, effective, and reusability. In this research, we used Moringa oleifera leaf extract-mediated CeO2NPs. CeO2NPs were characterized by XRD, FTIR, SEM, TEM, and DRS UV-vis. The photocatalytic activity of CeO2NPs was tested using a phenol dye concentration of 7 mg/L with variations in photocatalyst weight of 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 mg under UV irradiation, respectively, with time variations of 15, 30, 45, 60, 75, 90, 105, 120, 135, and 150 min. SEM and TEM morphology results showed that the CeO2NPs were spherical and agglomerated. The crystal structure is cubic, with a crystal size of 18 nm with a band gap of 2.87 eV. CeO2NPs showed high photo-degradation phenol dye of 94.45% under visible light in 120 min irradiation time. The results show that M. oleifera leaf extract could be as inexpensive and safe for synthesizing other metal oxide nanoparticles, potentially having applications in the biomedical and environmental fields.

氧化铈纳米粒子的绿色方法及其在光降解苯酚染料中的应用

利用植物作为封端剂合成氧化铈纳米粒子（CeO2NPs）的方法因其环保、低成本、简单、有效和可重复使用而被广泛研究。在这项研究中，我们使用了油辣木叶提取物介导的 CeO2NPs。通过 XRD、FTIR、SEM、TEM 和 DRS UV-vis 对 CeO2NPs 进行了表征。在紫外线照射下，使用浓度为 7 mg/L 的苯酚染料测试 CeO2NPs 的光催化活性，光催化剂重量分别为 10、20、30、40、50、60、70、80、90 和 100 mg，时间分别为 15、30、45、60、75、90、105、120、135 和 150 分钟。SEM 和 TEM 形貌结果表明，CeO2NPs 呈球形和团聚状。晶体结构为立方体，晶体尺寸为 18 nm，带隙为 2.87 eV。在可见光下，CeO2NPs 在 120 分钟的照射时间内对苯酚染料的光降解率高达 94.45%。研究结果表明，油橄榄叶提取物可用于合成其他金属氧化物纳米粒子，且成本低廉、安全性高，有望在生物医学和环境领域得到应用。
