V-doped In2O3 nanofibers for H2S detection at low temperature
Source abstract
Abstract
Abstract Pristine and vanadium-doped In 2 O 3 nanofibers were fabricated by electrospinning and their sensing properties to H 2 S gas were studied. X-ray diffractometry (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to investigate the inner structure and the surface morphology. The H 2 S-sensing performances were characterized at different temperatures ranging from 50 to 170 °C. The sensor based on 6 mol% V-doped In 2 O 3 nanofibers exhibit the highest response, i.e. 13.9–50 ppm H 2 S at the relatively low temperature of 90 °C. In addition, the fast response (15 s) and recovery (18 s) time, and good selectivity were observed.
