Supra Hydrolytic Catalysis of Ni₃ Fe/rGO for Hydrogen Generation.

ABSTRACT: Light metal hydrolysis for hydrogen supply is well suited for portable hydrogen fuel cells. The addition of catalysts can substantially aid Mg hydrolysis. However, there is a lack of clear catalytic mechanism to guide the design of efficient catalysts. In this work, the essential role of nanosized catalyst (Ni₃ Fe/rGO) in activating micro-sized Mg with ultra-rapid hydrolysis process is investigated for the first time. Here, an unprecedented content of 0.2 wt% Ni₃ Fe/rGO added Mg can release 812.4 mL g^-1 hydrogen in just 60 s at 30 °C. Notably, an impressive performance with a hydrogen yield of 826.4 mL g^-1 at 0 °C in only 30 s is achieved by the Mg-2 wt% Ni₃ Fe/rGO, extending the temperature range for practical applications of hydrolys
