Nano-confined multi component metal hydride system for hydrogen sensing application

Hydrogen has been portrayed as a new alternative for the energy source to replace non-renewable energy sources such as fossil fuel. Hydrogen is going to be a prime part of the fuel cells, particularly for automobiles. Hydrogen energy is also useful for space applications, as combustion of hydrogen can provide very high energy densities as compared to other energy sources. Safety is a crucial aspect while handling hydrogen as it is highly flammable above its lower explosion limit. In our work, we studied the hydrogen sensing properties of the metal hydride namely Pd, Pt impregnated graphitic carbon nitride (g-C3N4) nanocomposite, and metal oxide ZnO impregnated graphitic carbon nitride nanocomposite at room temperature. We studied the various important factors such as response and recovery time, stability, and the sensitivity of the sensor at room temperature.
