Abstract: A novel Ce-ZnSnO3material was synthesized by hydrothermal method based on the actual detection demand of n-butanol gas in chemical plants. The crystal structure, microstructure and oxygen defect content of the material were characterized by XRD, SEM, TEM and XPS. The feasibility of Ce-ZnSnO3 as coating material for gas sensor was studied. The results showed that the response of the material to n-butanol gas with concentration of 0.01% at 350 ℃ is 2 606.473, the response/recovery time is only 6 s/26 s, and the material has excellent selectivity,which is promised sensing material for the detection of n-butanol gas.

Key words: hydrothermal, ZnSnO3, n-butanol, gas sensor
