摘要: Abstract Hydrogen is one of the best alternative to petroleum as an energy carrier. However, development a Hydrogen-based economy requires commercialization safe and cost-effective storage system. In this paper, alloys belonging Mg–Zr–Mn–Ni alloy system are synthesized using high ball milling method. The particle size evolution, chemical analysis nano-scaled structures were characterized by SEM, EDXS XRD techniques, respectively. optimized - highest hydrogen storing has about 8.36 ± 1.17 μm with crystallite 16.99 ± 5.48 nm. absorption-desorption measurement carried out on principle pressure reduction coded MZ1 shows uptake greater than 7 mass % H2 at charging temperature 200 °C, indicating gravimetric capacity relatively lower hydriding temperature. also considerably enhanced – dehydriding kinetics, compare pure Mg.
