研究目的
To synthesize nanosized CoFe2O4 through an eco-friendly and cost-effective Aloe vera-mediated sol-gel auto-combustion method for high frequency devices.
研究成果
The study successfully synthesized CoFe2O4 nanoparticles using an eco-friendly method, demonstrating high dielectric constant and low loss, making it suitable for high-frequency applications. The material also showed promising magnetic properties for magneto-recording devices.
研究不足
The study is limited by the synthesis method's dependency on the Aloe vera extract's quality and the need for further optimization to enhance the material's properties for specific applications.
1：Experimental Design and Method Selection:
The synthesis of CoFe2O4 nanoparticles was carried out using the sol-gel auto-combustion method with Aloe vera leaf extract as a reducing and gelling agent.
2：Sample Selection and Data Sources:
Metal nitrates (Cobalt Nitrate and Ferric Nitrate) were used as precursors, and Aloe vera leaf extract was prepared by boiling the leaves in millipore water.
3：List of Experimental Equipment and Materials:
The synthesis involved the use of a muffle furnace, FTIR spectrometer, X-ray diffractometer, FE-SEM, LCR meter, and VSM for characterization.
4：Experimental Procedures and Operational Workflow:
The metal nitrates solution was mixed with Aloe vera extract, stirred, and then heated in a muffle furnace. The resulting powder was characterized for structural, morphological, dielectric, and magnetic properties.
5：Data Analysis Methods:
The data obtained from various characterizations were analyzed to confirm the formation of single-phase CoFe2O4 and to study its properties.
