Detection of low concentration hydrogen gas using highly sensitive three-dimensional palladium decorated graphene encapsulated in poly (methyl methacrylate)

Hydrogen gas (H2) is known as one of the cleanest and most promising energy sources for future energy related applications in transportations and power generations due to its energy density, renewability, and ecofriendly in nature. However, the use of hydrogen gas is associated with serious safety concerns since it is highly flammable due to low spark ignition energy (0.02 mJ) and explosive when mixed with air at volume concentrations higher than 4%. Thus, systems utilizing hydrogen as an alternative fuel requires fast, accurate and constant monitoring for the leaks. In this research work, graphene foam doped with palladium nanoparticles will be developed as the sensing element as it has large surface area that provides huge, highly sensitive and selective gas adsorptive capacity. The proposed graphene foam sensor will have fast response and recovery time that lead to low power consumption and miniaturization of the device.
