High Sensitive Manganese Nickel Ferrite Nanoparticles as AcetoneSensor

In this study, nickel-manganese ferritenanoparticles with a diameter of less than ۲۰ nm wereprepared. Using X-ray diffraction, scanning electronmicroscope (SEM) and X-ray fluorescence spectroscopy (XRF),the morphology and structure of this ferrite was investigated. Xrayanalysis shows the formation of nickel-manganese ferrite inthe spinel phase. The SEM image shows the spherical shape ofthe nanoparticles and X-ray fluorescence spectroscopy confirmsthe presence of iron, nickel and manganese. The crystal size ofnickel-manganese ferrite nanoparticles, calculated by theDebye-Sherrer relation, has been calculated to be close to ۸.۳۶nm. The sensitivity property of this ferrite was investigated byexposing the ferrite to different gas samples. Four gasesethanol, methanol, carbon tetrachloride and acetone weretested in this study. Among these samples, acetone had the bestsensitivity performance. Finally, the equation of acetone sensorwas derived by applying different concentrations from ۲۰ to ۲۰۰ppm.
