| Abstract: | Co-SnO2 composite nanofibers were synthesized by an electrospinning method and characterized by X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy. Gas sensors were fabricated by spinning these nano- fibers onto flat ceramic substrates, which had signal electrodes and heaters on their top and bottom surfaces, respectively. Com- pared with sensors loaded with pure SnO2 nanofibers, the Co-SnO2 nanofiber sensors exhibited improved acetone sensing proper- ties w... |
