FeNiCu-based composite catalysis proves to be an effective strategy for enhancing the hydrogen storage performance of MgH2. Two catalysts; (Cu0.2Ni0.8) O/NiFe2O4 and FeNi3/Fe4Cu3; are successfully synthesized and doped into MgH2 to improve its hydrogen storage capability. Experimental results demonstrate that MgH2 + 5 wt% (Cu0.2Ni0.8)O/NiFe2O4 (MgH2 + 5 A) and MgH2 + 5 wt% FeNi3/Fe4Cu3 (MgH2 + 5B) composites desorption at 171 ℃ and 178 ℃; respectively; which is 100 ℃ lower than that of ball-milled MgH2. Under conditions of 150 ℃ and 3 MPa; MgH2 + 5 A can absorb 6.02 wt% H2 in just one minute. MgH2 + 5B; at; 225/325; ℃; exhibits hydrogen absorption/desorption exceeding 7 wt% H2 for 1 h. The synergistic effect of in situ formed Mg2Ni and Fe positively impacts the hydrogen storage behavior of MgH2. The introduced interface offers numerous low-energy barrier H-diffusion channels; resulting in accelerated release and hydrogen absorption. Additionally; Cu4O3 dispersed on the surface of the matrix particles maintains its valence during the process of hydrogen absorption/desorption. This property can facilitate the conversion of Mg2Ni/Mg2NiH4 into a hydrogen pump. This study provides an experimental basis and new insights for designing highly efficient catalysts for Mg-based hydrogen storage materials. © 2024 Elsevier B.V;
