Abstract
This study reports the development of a Pd functionalized graphene-based chemiresistor device for the detection of hydrogen at room temperature. This low-cost graphene device can operate and detect hy-drogen efficiently at room temperature and hence has a very low power unlike pellistor-based sensors.Our preliminary data clearly reveal that the sensor can detect hydrogen at concentrations ranging from 0.01 % to 1 % hydrogen in air. This shows the potential of a graphene chemiresistor to be used for detection of hydrogen leaks in, for example H₂-based cars emerging to replace combustion engines.
