Abstract
In this paper, NdFeO3 nanoparticles were prepared by thermal treatment method and subsequent annealing at 700 °C. The morphological and microstructural features of NdFeO3 nancrystals were investigated by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). NdFeO3 nanoparticles were used for the fabrication of conductometric sensors for monitoring acetone in air. The effect of NdFeO3 loading and operating temperature on sensing performance was investigated. Results of sensing tests indicate that NdFeO3 nanoparticles exhibit good response to low concentration of acetone (2–40 ppm) in air at 200 °C. Finally, the developed NdFeO3 sensor showed also excellent selectivity to acetone over other interfering gases such as CH4, CO, CO2, H2, NH3, NO2 and NO.
