【摘要】：采用水热法合成了钨酸铁纳米材料,应用XRD和SEM对钨酸铁纳米材料进行了表征和分析,研制了一种基于YSZ的混合电位型FeWO_4/YSZ/Pt氢气传感器.在500℃时,氧气浓度为10%条件下,基于YSZ的钨酸铁传感器对浓度80~960 ppm的H_2有着良好的气敏性能,并对CO,C_3H_8,NO_2这些可能的干扰气体有着优异的选择性,传感器同时具有良好的重复性和一致性.与已有的MnWO_4/YSZ/Pt和CdWO_4/YSZ/Pt氢气传感器对比发现FeWO4/YSZ/Pt氢气传感器性能更佳.
[Abstract]:Ferric tungstate nanomaterials were synthesized by hydrothermal method. The XRD and SEM were used to characterize and analyze the iron tungstate nanomaterials. A hybrid potential FeWO_4/YSZ/Pt hydrogen sensor based on YSZ was developed. At 500 C, the oxygen concentration was 10%, and the YSZ based ferric acid ferric sensor had good gas sensitivity to the H_2 of the concentration 80~960 ppm. Performance, and has excellent selectivity for possible interfering gases such as CO, C_3H_8, NO_2. The sensor has good repeatability and consistency. Compared with existing MnWO_4/YSZ/Pt and CdWO_4/YSZ/Pt hydrogen sensors, the performance of FeWO4/YSZ/Pt hydrogen sensor is better.
