本文介绍了一种高灵敏度的可燃气体传感器，用于选择性地检测氢气和其他可燃气体。配体，4,4”-二氨基对terphenyl (DATER)，连接Pt纳米颗粒首次被用作氢气检测的催化剂。该传感器具有非常高的灵敏度，在110°C工作温度下，对0.1%的氢气具有31 mV的灵敏度，并且与氢气浓度呈完全线性特性。它在较低温度下工作时消耗极低的功率，90°C时为14 mW。此外，该传感器在其工作温度和更高温度下对甲烷和乙烷没有交叉灵敏度。
This paper presents a highly sensitive combustible gas sensor for detecting hydrogen gas selectively against other combustible gases. Ligands, 4,4"-Diamino-p-terphenyl (DATER), linked Pt nanoparticles are used for the first time as a catalyst for hydrogen gas detection. The sensor has very high sensitivity, 31 mV for 0.1% hydrogen at 110 °C operating temperature and shows completely linear characteristics with the concentration of hydrogen. It consumes extremely low power while operating at lower temperature, 14 mW at 90 °C. Moreover, the sensor has no cross-sensitivity to methane and ethane at its operating temperature as well as at higher temperature.
