Effects of Ni, Fe2O3, and CNT addition by reactive mechanical grinding on the reaction rates with H2 of Mg-based alloys

► Content of the additives of about 20 wt %, and 6 wt% of oxide addition. ► Preparation of Mg-14Ni-6Fe2O3, and Mg-14Ni-6Fe2O3-2CNTby RMG. ► Effects of Ni, Fe2O3, and CNT addition on hydriding and dehydriding rates. ► Addition of Ni and Fe2O3 increases hydriding rate and/or dehydriding rate. ► CNT Addition made activation process unnecessary with a small decrease in capacity.
