To effectively address the kinetic sluggishness associated with MgH2, this study utilized Ti-EG-Ni dual-metal organic crystal as precursors and employed carburization to prepare unique rod-shaped structure TiO2/C/Ni. The catalyst was incorporated into MgH2 by ball milling, demonstrating excellent hydrogen storage performance. composite of MgH2-8 wt % TiO2/C/Ni exhibited a lower initial dehydrogenation temperature 185 °C marked activation energy 60.537 kJ/mol. At 300 150 °C, it only required s release 6.17 H2 absorb 5.72 within 20 s, respectively. Additionally, composites demonstrated cycling stability, maintaining 94% reversible capacity after 50 cycles. Theoretical computations suggested that in situ-generated metal Mg2Ni semiconductor TiO2 created Schottky heterojunction, which stimulated an internal electric field between Ni TiO2, accelerating electron transfer. strong electronic interaction weakened Mg-H bond elongated bond, promoting dissociation. During absorption desorption, material performance due uniform distribution elements, catalytic active sites (multivalent Ti Mg2Ni/Mg2NiH4), support provided carbon nanostructures. Our findings provide deeper understanding how highly catalysts oxides/C/Ni enhance MgH2.
