Abstract
In this paper, NdFeO3 nanofibers were synthesized by the electrospinning method for the first time and used for the detection of triethylamine. XRD, SEM, TEM, BET, XPS, and gas-sensitive test instruments were used to detect the morphology, structure, and gas-sensitive properties of the synthesized products. The results show that the average diameter of the nanorods is about 275 nm. The specific surface area is 10.298 m2/g, the total pore volume is 0.112 cm3/g, and the average pore diameter is 43.469 nm. Gas sensing tests were carried out on NdFeO3 nanofibers. The gas-sensitized element was found to have a low optimal operating temperature of 190 °C. The response to 100 ppm triethylamine was 18.9. The response time and recovery time were 72 and 35 s, respectively. A series of test results showed that the sample had excellent selectivity, reproducible detection, long-term stability, and a low detection limit for triethylamine. It has a lot of potential for practical TEA monitoring and detection.
