Historically, production of high-performance gas sensing materials has promised to satisfy the worldwide research interests with the increasingly enhanced gas sensor devices. In this paper we are adopting a facile hydrothermal strategy to prepare the ternary FeCo₂O₄/graphene hybrid nanocomposites. The spinal phase of FeCo₂O₄ with spherical shaped morphology was obtained through XRD, SEM and TEM images which confirms. In addition, an average particle size within the range of 30-40 nm was observed for the individual spherical shaped morphology. The Raman and XPS studies also explore the vibration modes and chemical composition of the FeCo₂O₄/graphene composites. The BET surface area and BJH pore size of FeCo₂O₄/graphene composites is estimated to be 93.2 m²/g and 19.45 nm, respectively. Such high surface area will provide the active path to gas molecules which will increase the efficiency of gas sensing. Measurement of ethanol and acetone gas sensing using clad altered fiber optic sensors and sensitivities for ethanol and acetone gases are 22 and 43 counts/ppm, respectively. Also discussed is the proposed gas sensing mechanism.

从历史上看，高性能气体传感材料的生产已承诺随着日益增强的气体传感器设备的出现，将满足世界范围内的研究兴趣。在本文中，我们采用一种简便的水热策略来制备三元FeCo ₂ O ₄ /石墨烯杂化纳米复合材料。通过XRD，SEM和TEM图像获得了具有球形形态的FeCo ₂ O ₄的脊柱相。另外，对于各个球形形态观察到在30-40nm范围内的平均粒度。拉曼和XPS研究还探索了FeCo ₂ O ₄的振动模式和化学成分。/石墨烯复合材料。FeCo ₂ O ₄ /石墨烯复合物的BET表面积和BJH孔径估计分别为93.2 m ² / g和19.45 nm。如此高的表面积将为气体分子提供主动路径，这将增加气体感测的效率。使用包层改型的光纤传感器测量乙醇和丙酮气体的灵敏度，对乙醇和丙酮气体的敏感度分别为22和43个计数/ ppm。还讨论了提出的气体传感机制。
