摘要/Abstract

摘要： 基于化工厂对正丁醇气体的实际检测需求,采用水热法合成了一种新型的Ce-ZnSnO₃材料,通过XRD、SEM、TEM及XPS对材料的晶体结构、微观形貌以及氧缺陷含量进行了表征,并研究了基于Ce-ZnSnO₃材料作为气敏传感器涂层材料的可行性.结果表明:在350 ℃条件下,该材料对体积分数0.01%的正丁醇气体的响应值达2 606.473,响应/恢复时间仅为6 s/26 s,同时具有优异的选择性可成为一种检测正丁醇气体的传感材料.

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.
