A variety of research endeavors are directed to development of an alternative energy pathway of fossil fuels, which can reduce the emission of CO2, CO, due to burning of fossil fuels and reduce our over dependence on the fossile fuels.. In this regard, we report here, the generation of H2, a convenient, eco-friendly fuel from the Hydrazine oxidation reaction (HzOR) at room temperature. An intriguingly superior high entropy nano-catalyst comprises of five elements (Ag, Au, Pt, Pd, Cu) prepared by the casting-cum-cryomilling method, which endowed with unique catalytic activity was explored for HzOR. The continuous production of H2 elucidated that the catalyst is quite stable for the HzOR reaction at low overpotential, with no sign of ammonia formation. The reaction pathways leading to generation of hydrogen with nitrogen are discussed and deliberated.
