| 摘 要： | 采用正交试验法和单水平试验法研究了热处理温度及掺杂元素对ＷＯ３基Ｈ２Ｓ气敏元件灵敏度、选择性、稳定性，响应恢复特性及元件阻值的影响，得到了较为理想的Ｈ２Ｓ气敏元件。根据提出的气敏机理模型较好地解释了热处理温度、掺杂氧化物酸碱性及催化活性等对Ｈ２Ｓ气体灵敏度的影响。

| Abstract: | Effects of heat treatment temperature and dopant on gas sensitivity, selectivity, stability, response and recovery time, and sensor resistance of WO 3_based gas sensors were studied by means of orthogonal experiments and single level experiments, then a satisfactory H 2S gas sensor was obtained. Based on the proposed gas sensitivity model in literatures, influence of heat treatment temperature, acid_base properties and catalytical activity of doping oxide on gas sensitivity of the gas sensor was explained. |
