The growth of ultra-thin and uniform TiO2 coating on carbon nanofibers (CNFs) by a non-aqueous Atomic Layer Deposition (ALD) approach, as well as their structural characterization and electrical properties investigation, have been reported. The NO2 gas sensing behavior of these titania-coated carbon nanofibers was studied by fabricating resistive-type sensors and measuring changes in electrical resistance with respect to concentration and time.

Abstract
The growth of ultra-thin and uniform TiO2 coating on carbon nanofibers (CNFs) by a non-aqueous Atomic Layer Deposition (ALD) approach, as well as their structural characterization and electrical properties investigation, have been reported. The NO2 gas sensing behavior of these titania-coated carbon nanofibers was studied by fabricating resistive-type sensors and measuring changes in electrical resistance with respect to concentration and time. In contrast to pure CNFs, the hybrid sensors responded to NO2 at near room temperature, evidencing unprecedented p-type responsiveness.File in questo prodotto:
