Abstract:Fe3O4-C nanostructured composites were used for the fabrication of thin films as active layers in resistive chemical sensors. Nearly spherical and like-sheet porous structures were obtained via green method using olive leaf extract (OLE) followed by thermal process at 300°C and 550°C, respectively, for high-performance gas sensing applications. The prepared sensors were measured with various concentrations of toxic gases such as acetone (C3H6O), ethanol (C2H5OH), and carbon dioxide (CO2) at different operating… Show more
