Developing catalysts with exceptional catalytic activity is crucial in solid hydrogen storage. Two catalysts, NiO/NiCo2O4 and NiO/NiFe2O4/Ni, are successfully prepared incorporated into MgH2 for the first time to investigate storage properties of MgH2. The experimental results indicate that desorption temperatures composites + 5 wt % (MgH2 NC) NiO/NiFe2O4/Ni NF) occur at 241 175 °C, respectively. Hydrogen ball-milled begins 272 °C. Both NF NC exhibit excellent absorption kinetics. At 150 °C 3 MPa, can absorb 5.93 5.95 H2 as little 1 min, activation energies 88.38 81.56 kJ/mol, respectively, compared pure MgH2, which has an Ea 181.4 kJ/mol. Furthermore, cycle experiments demonstrate both display stability, maintaining capacities approximately 99.8 98%, after 10 cycles. In situ formed Fe extends defect structure interfaces thus providing additional diffusion channels. Moreover, embedded clusters Mg2NiH4/Mg2CoH5 function "multistage pumps", surface pathways efficient absorption. This study offers evidence novel insights aimed enhancing kinetic performance
