Abstract

Hydrogen sulfide poses a significant threat to the atmospheric environment and human health. To leverage the advantages of nanofiber film and heterojunction, a novel yttria-stabilized zirconia@SnS₂/Bi₂S₃ composite nanofiber consisting of yttria-stabilized zirconia nanofibers anchored with SnS₂ nanosheets and decorated with Bi₂S₃ was designed. The gas sensor demonstrated high response of 1090 %, rapid response/recovery speed of 60/135 s towards 1 ppm hydrogen sulfide at room temperature. This study may offer a novel strategy for the development of composite nanofiber materials for gas sensors.
