摘要：
Herein, we report the synthesis and characterization of SnO2 nanopowders prepared by hydrothermal process. The gas absorption properties of the material are characterized by electrochemical workstation. The results show that the response and recovery time of the sensor to 100 ppm H-2 are decreasing with rising of temperature, which the same law is found to CO sensing. The selective of the sensor to both H-2 against CO and the n value of the sensor to H-2 and CO are also presented and discussed.
