چکیده انگلیسی
In the present work, α-Fe2O3 nanoparticles were successfully synthesized by Pechini sol-gel (PSG) method following annealing at 550 °C. The morphology and microstructure of the prepared α-Fe2O3 nanoparticles were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman analysis. The electrical and sensing properties were also investigated. The α-Fe2O3 based sensor showed good sensitivity and selectivity towards ethanol at the optimal temperature of 225 °C. Moreover, the sensor displayed good electrical and sensing stability. These results suggest the potential applications of α-Fe2O3 synthesized by Pechini sol-gel method as a sensor material for ethanol detection.
