DU Hui1, NIU Xin-shu1, JIANG Kai1. Preparation and gas sensitivity properties of nanometer ZnSnO3 powders[J]. 2007, (4): 14-17. DOI: 10.13873/j.1000-97872007.04.012.
ZnSnO3 powders is synthesized by sol-gel method in the system of citric acid with Sn and Zn as the starting materials.The structure and crystal state of the powder are determined on an X-ray diffractometer(XRD).The shape and size are analyzed with the help of transmission electron microscopy(TEM).The results show the mean grain size of the powder is about 10 nm.The study of sensor’s gas-sensing characteristic reveals that the gas sensors based on ZnSnO3 powders have good gas-sensing properties to ethano1
acetone and H2S.The gas-sensing properties of the ZnSnO3 powders calcined at 600 ℃ to acetone of volume fraction 50×10-6is especially good
the ratio of resistance is 69 at 360 ℃.The response and recovery times are 10s and 5 s.
