摘要：
A Titanium dioxide (TiO2)/multi wall carbon nanotubes (MWCNTs) nanocomposite was synthesized by hydrothermal process. X-ray diffractometry, transmittance electron microscopy observation revealed this nanocompsite has high nanocrystral structure. After blending with regenerated cellulose, this hybrid nanocomposite was used as a room temperature ammonia (NH3) gas sensor. The TiO2/MWCNTs hybrid nanocomposite exhibited much higher response and faster response-recovery to NH3 gas of concentration ranging from 3000 ppm to 9000 ppm. The TiO2/MWCNTs hybrid nanocomposite can be a flexible room temperature gas sensor. The gas sensing mechanism of this hybrid nanocomposite is also discussed in this paper.
