- Abstract
For the low-cost and non-polluting characteristics of hydrothermal process' novel zinc oxide nanoshuttles were prepared by zinc nitrate' hexamethylenetetramine and ammonia hydrothermal system. The formation of zinc oxide nanoshuttles was analyzed. Zinc oxide nanoshuttles were used to prepare indirectly heated gas sensors and tested for alcohol gas sensitivity by a Labview gas sensing data acquisition system. The operation temperature of this material was about 380 °C. Different gas tests showed that this material owned the highest sensitivity to ethanol than other gas at this temperature. The sensitivity for 5 x 10 ethanol was reached 40%. The sensitivity increased with the ethanol concentration increased. The sensitivity reached to 85% until the ethanol concentration reached 100 x 10-6.
