Özet
Safety is extremely important in hydrogen energy applications due to combustion taking place very quickly when hydrogen and air are mixed at a rate of about 4% in the ambient. For the detection of hydrogen, hydrogen sensors with high sensitivity and fast response times need to be developed. In sensor technologies, palladium (Pd)-based materials are in-depth research as they detect hydrogen with high sensitivity and short response time at room temperature. The nanoflower morphology increases the sensing surface significantly, thus affecting the sensitivity. Therefore, in this study, a novel process for the preparation of a 3D self-assembled Pd nanoflower-based sensor was reported, and the hydrogen detection performance of the sensor was investigated. From the XRD spectrum, (1 1 1), (2 0 0), and (2 2 0) diffraction peaks correspond to the FCC crystal structure of Pd nanoflowers. Sensor measurements reveal that the sensitivity and the limit of detection (LOD) of the sensor were 10 and 100 ppm at room temperature, respectively. The response time of the sensor was to be 90 s and the recovery time was 120 s at 4000 ppm. Measurements reveal that the prepared Pd nanoflower-based sensor has high sensitivity and a short response time against hydrogen at room temperature. The sensor can be used for the detection of hydrogen leakage.
