摘要 报道了银掺杂的半导体氧化物CuO-BaTiO_3对CO_2的敏感特性。分析了Ag掺杂量对CuO-BaTiO_3灵敏度的影响。Ag掺杂量不仅影响CuO-BaTiO_3对CO_2是的灵敏度和工作温度,还影响材料在空气中的电阻值。通过适当量的Ag掺杂提高了CuO-BaTiO_3的化学活性,增强了对CO_2的吸附和反应,使传感器对CO_2的灵敏度提高。银掺杂的CuO-BaTiO_3传感器对CO_2的检测范围为1.0×10^(-4)到10％,最小检测浓度为1.0×10^(-4)。还对银掺杂后的稳定性进行了分析。 The characteristics of Ag - doped CuO - BaTiO3 based CO2 gas sensor was investigated. The sensitivity of the CuO - BaTiO3 sensor with doping ratio of Ag was analyzed. The doping ratio of Ag element influences sensitivity, operating temperature, and resistance of the sensor. By adding appropriate amounts of Ag, the chemical activity of CuO - BaTiO3 is increased, and the sensitivity is strengthened. The detection range for the Ag - doped CuO - BaTiO3 is from 1.0×10-4to 10% of and lowest detection is 1. 0 × 10 -4 of CO2. Stability of Ag - doped CuO - BaTiO3 was also analyzed.
