Improved H2S sensing properties of Ag/TiO2 nanofibers
Source abstract
Abstract
Abstract Pristine and Ag nanoparticle modified TiO 2 nanofibers were fabricated by an electrospinning technique using polyvinyl pyrrolidone (PVP) and tetrabutyl titanate as precursor. The morphology and structure of the as-synthesized nanofibers were characterized by scanning electron microscopy and X-ray diffraction. It was found that the presence of Ag had a significant effect on the morphology and crystal structure of TiO 2 nanofibers, and that Ag addition could promote the phase transformation from anatase to rutile. H 2 S sensing properties of the sensors based on TiO 2 nanofibers were also investigated. The results showed that Ag/TiO 2 nanofibers exhibited better gas sensing performances than pristine TiO 2 nanofibers and the possible sensing mechanism was discussed.
