摘要：

Multiwalled carbon nanotubes (MWNTs) were prepared by chemical vapor deposition. Then the heater-type gas sensor was made by doping MWNTs in ZnO powder. The morphology of MWNTs-doped ZnO powder was characterized by scanning electron microscope (SEM). The studies reveal that the sensitivity of ZnO gas sensor is significantly improved with the addition of MWNTs. The sensitivity of the sensor is 46 and the response and recovery times are 4 and 20 s respectively when the concentration of ethanol is 5.0×10-5. It also shows the prominent selection to common interference gases.
