摘要：

Sn-doped MoO3 were synthesized by a hydrothermal method, using ammonium paramolybdate and tin tetrachloride as raw materials. The structure, morphology and pore texture of the samples were characterized by means of X-ray diffraction(XRD), scanning electron microscope(SEM) and Brunauer-Emmett-Teller (BET). The gas sensing properties of ethanol, dichloromethane, methanol, formaldehyde, formic acid, carbon tetrachloride, ammonia and acetone were tested. The results show that Sn doping does not affect the structure of MoO3 and the best heating temperature is 290 degrees C. After Sn doping, the sensitivity is better than the pure MoO3, and the response time is shorter. MoO3 doped with 5%(molar ratio) Sn shows the best gas sensing properties, with a gas sensitivity of 19. 64 and a rapid response time of 1. 1 s in 500 mg/m(3) of ethanol.
