Abstract

This research has successfully performed a new environmentally friendly, safe, and harmless method for fabricating Bi₂Ce₂O₇ nanoparticles (NPs) using Elaeis guineensis Jacq. leaf extracts. Based on the FT-IR measurement, the absorption peak at 635 cm⁻¹ indicates the Bi-O-Ce stretching vibration. The crystalline structure analysis showed that the monoclinic phase of Bi₂Ce₂O₇ NPs was proven by X-ray diffraction characterization. UV–Vis DRS results show that Bi₂Ce₂O₇ NPs have a narrow bandgap of 2.48 eV, indicating their potential for visible light photocatalytic applications. The shape of Bi₂Ce₂O₇ NPs was spherical in agglomeration with an average size of about 30.15 nm. Bi₂Ce₂O₇ NPs exhibited exceptional photocatalytic activity for the degradation of methylene blue (MB) and malachite green (MG) dyes under visible light irradiation. Degradation rates of 99.7 % and 95.8 % for MB and MG, respectively, were achieved within 90 min. This study highlights the potential of utilizing plant-based extracts to produce efficient and environmentally friendly photocatalytic materials.

用桉树叶提取物合成的 Bi2Ce2O7 纳米粒子及其光催化应用潜力叶提取物及其光催化应用潜力

本研究成功地利用桉树叶提取物制备了一种环保、安全、无害的新型 Bi2Ce2O7 纳米粒子（NPs）。根据傅立叶变换红外光谱测量，635 cm-1处的吸收峰表示Bi-O-Ce伸缩振动。晶体结构分析表明，X 射线衍射表征证明了 Bi2Ce2O7 NPs 的单斜相。紫外可见 DRS 结果表明，Bi2Ce2O7 NPs 具有 2.48 eV 的窄带隙，表明其具有可见光光催化应用的潜力。Bi2Ce2O7 NPs 的团聚形状呈球形，平均尺寸约为 30.15 nm。在可见光照射下，Bi2Ce2O7 NPs 在降解亚甲基蓝（MB）和孔雀石绿（MG）染料方面表现出卓越的光催化活性。在 90 分钟内，亚甲基蓝和孔雀石绿的降解率分别达到 99.7% 和 95.8%。这项研究凸显了利用植物萃取物生产高效环保光催化材料的潜力。

期刊介绍： Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences. A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below. The scope of the journal includes: 1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes). 2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis. 3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification. 4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
