The synthesis of the FeO-CuO-CuFeO nanocomposite was effectively achieved through the sol-gel technique, utilizing ethanol as a reactive fuel. Investigation of the nanocomposite's structure via X-ray Diffraction confirmed the coexistence of FeO, CuO, and CuFeO phases within the material. The Scherrer equation was applied to determine an average crystallite size ranging from 60 to 95 nm. UV-visible spectroscopy studies suggested the material possesses an approximate energy bandgap of 4 eV. Scanning Electron Microscopy provided insights into the nanocomposite's surface morphology, which exhibited a porous and heterogeneous aggregation of particles in various sizes and shapes. When tested for antibacterial efficacy, the nanocomposite exhibited activity against gram-positive S. aureus with a maximum zone of inhibition (ZOI) measuring 9 mm at the highest concentration, whereas no inhibitory effect was detected against gram-negative E.coli.
通过溶胶-凝胶技术，以乙醇作为反应性燃料，有效合成了FeO-CuO-CuFeO纳米复合材料。通过X射线衍射对纳米复合材料的结构进行研究，证实了材料中FeO、CuO和CuFeO相的共存。应用谢乐方程确定平均微晶尺寸范围为60至95纳米。紫外-可见光谱研究表明该材料的近似带隙为4电子伏特。扫描电子显微镜提供了对纳米复合材料表面形态的见解，其呈现出各种尺寸和形状的颗粒的多孔且不均匀的聚集。在测试抗菌功效时，该纳米复合材料对革兰氏阳性金黄色葡萄球菌表现出活性，在最高浓度下最大抑菌圈（ZOI）为9毫米，而对革兰氏阴性大肠杆菌未检测到抑制作用。
