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.
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.
