摘要
研究了甲烷浓度和工作温度对氧化锆基混合电位型传感器响应值的影响。以氧化钇稳定的氧化锆(YSZ)为固体电解质,氧化锡(SnO_2)为工作电极的传感器对(200~1 000)×10^(-6)浓度的甲烷具有良好的传感性能,传感器响应值与甲烷浓度的对数值呈良好的线性关系,传感器在650℃时具有良好的传感性能,其中响应时间和恢复时间均低至5 s。
Effects of methane concentration and operating temperature on zirconia-based mixed potential sensor responsing value are studied. Yttria-stabilized zirconia（YSZ） is adopted as electrolyte and SnO2 as sensing electrode for measurement.The sensor exhibits superior sensing characteristics to（200~ 1 000） × 10^（-6） methane. The sensor response indicates a log-linear relationship with the methane concentration. The sensitivity of the sensor is high at 650 ℃,and the response and recovery time are less than 5 s.
