英文摘要：

NASICON （sodium super ionic conductor） solid-electrolyte and Ni/Ti compound oxide materials were prepared by sol-gel method. And solid-electrolyte H2S gas sensor was fabricated with NASICON as the ion electric layer and Ni/Ti compound oxide as the sensing electrode. The sensor using Ni/Ti compound oxide as the sensing electrode exhibited well sensing performances to 1 ·10^-6 -100· 10^-6 H2S at 260-380℃. The sensitivity （slope） of the sensor was -72.4 mV/decade at 320℃. Also the sensor exhibited well selectivity, resistance against water humidity and response-recovery characteristics. The response time of the sensor to 5 · 10^-6, 50· 10^-6 H2S was 10 s,4 s and recovery time was 20 s,40 s, respectively. At last the sensing mechanism of the sensor was investigated.
