Popis: 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.
