چکیده انگلیسی
In this study, the perovskite praseodymium ferrite (PrFeO3 hollow nanofibers) was successfully synthesized via a facile electrospinning and calcination procedure. The structure, elemental composition and morphology were investigated by XRD, EDX, SEM and TEM. And the results of BET indicated that samples had a large specific surface area (33.74 m2/g) with mesoporous characteristics. The most importantly is that the gas sensor based on PrFeO3 hollow nanofibers possessed high response value, good selectivity and good long-time stability at a low operating temperature of 180 °C, even exposed to 10 ppm acetone, the sensor still delivered a response to be 6. Those good properties made it become the promising candidates for practical detectors to acetone.
