Electrospun LaFe1+XO3 nanotubes for enhancing gas sensing to n-butanol

Background It is imperative to monitor the levels of n-butanol in the environment for the preservation of ecosystems and safeguarding human health. As a potential substitute for n-butanol sensors, the LaFeO 3 nanofibers show encouraging promise. Methods We have used the electrospinning method to successfully construct a series of Fe doping LaFe 1+x O 3 ( x = 0, 0.03, 0.05, 0.07) nanotubes. Through the use of XRD, FESEM, TEM, and EDS, the sample's morphological structure and composition were examined. Significant findings With a quick response/recovery time of 9/15 s, the gas sensor based on LF 1.05 O 3 nanotubes showed a staggering response of 33.6 at 150 °C toward 100 ppm n-butanol. Compared to the other test gases, this sensor demonstrated remarkable n-butanol selectivity. Furthermore, a methodical examination of the sensing mechanism was carried out.
