摘要：A cataluminescence (CTL)-based gas sensor utilizing nano-sized Mn1.5Zr2O7 as the sensing material for the determination of hydrogen sulfide in air was proposed. The gas sensor showed high selectivity for hydrogen sulfide at 450 nm and satisfying activity at 320°C. The linear range of the CTL intensity versus concentration of hydrogen sulfide was 2~95 mg/m3, and the detection limit (3σ) was 1.5 mg/m3. No interference was observed while the foreign substances, such as formaldehyde, ammonia, ethanol, benzene, carbon monoxide and sulfur dioxide, were passing through the sensor. The gas sensor displayed good stability for continuously introducing hydrogen sulfide over 60 h, and allowed real-time monitoring of hydrogen sulfide in air. ?
