研究目的
Investigating the synthesis, structural, morphological, optical, photocatalytic and antibacterial activity of ZnO nanostructures by Pedalium Murex plant extract-assisted combustion method.
研究成果
ZnO nanoparticles and nano-sheets were successfully synthesized using Pedalium Murex plant extract. The ZnO-NPs showed enhanced photocatalytic and antibacterial activities compared to ZnO-NSs, attributed to their smaller particle size. The study demonstrates the potential of biosynthesized ZnO nanostructures for environmental and biomedical applications.
研究不足
The study focuses on the synthesis and characterization of ZnO nanostructures and their antibacterial and photocatalytic activities. Potential areas for optimization include the scalability of the synthesis methods and the efficiency of the photocatalytic degradation process.
1：Experimental Design and Method Selection:
ZnO samples with two different morphologies (nanoparticles and nano-sheets) were prepared by microwave heating (MHM) and modified sol–gel (SGM) method, respectively, using Pedalium Murex plant extract as the bio-reducing agent.
2：Sample Selection and Data Sources:
Zinc nitrate and Pedalium Murex plant extract were used as raw materials. The plant extract was prepared from Pedalium Murex leaves.
3：List of Experimental Equipment and Materials:
Rigaku Ultima IV high resolution powder X-ray diffractometer, Perkin Elmer FT-IR spectrometer, Jeol JSM6360 high resolution scanning electron microscope, Cary100 UV-Visible spectrophotometer, Varian Cary Eclipse Fluorescence Spectrophotometer.
4：Experimental Procedures and Operational Workflow:
The precursor mixture was exposed to microwave energy for nanoparticles synthesis and evaporated on a hot plate for nano-sheets synthesis. The samples were characterized by XRD, SEM, EDX, DRS, and PL spectroscopy.
5：Data Analysis Methods:
The crystallite size was calculated using Scherrer formula, and the band gap was measured using Kubelka-Munk method.
