Magnesium hydride (MgH2) has been recognized as a promising hydrogen storage material because of its low cost and high capacity. However, the sluggish kinetics operating temperature hindered utilization. Herein, vanadium-substituted titanium-based bimetallic MXene (Ti3-nVnC2) was prepared to boost efficiency MgH2. The incorporation 5 wt % Ti2.2V0.8C2 dramatically decreased dehydrogenation MgH2 improved cyclic stability. MgH2-5 started release at 165 °C, it released 7.0 H2 in 30 min 220 °C took 5.3 2 h 75 showing excellent kinetics. In addition, activation energy MgH2-added 80.81 ± 3.29 kJ mol-1, which is lower than that most Ti-/or V-based catalyst-doped systems. Mechanism analysis reveals remarkably enhanced performance ascribed stable existence uniform distribution Ti-species (Ti0 Titanium hydride) V-species (V0 V5+), facilitated rapid absorption/desorption ensured This study offers valuable perspectives for assembly design catalysts within realm solid-state materials.
