Abstract
The microstructures of mesoporous carbon nanofibers were characterized by scanning electron microscopy, transmission electron microscopy, nano-Raman, nitrogen adsorption-desorption and optical transmission. They possessed a high specific surface area 840 m2 g-1 and a 1.07 eV band gap. All mesoporous carbon nanofiber network can act as the channel material in p-type field-effect transistor devices with field-effect mobilities over 10 cm2/V s. Furthermore, mesoporous carbon nanofiber network exhibits better sensitivity and faster response to NO2 gas than that of carbon nanotubes, which makes it a promising candidate as poisonous gas sensing nanodevices.
