論文簡介如下：

To optimize the hydrogen storage performance of magnesium hydride (MgH₂), which is valued for its high capacity and abundance but suffers from slow de/hydrogenation kinetics, a strategic approach involving a high-performance catalyst is crucial. In this study, a Mn_1.48Ti_1.1V_0.3Zr_0.12 hydrogen storage alloy was chosen and processed into nanosheets to enhance MgH₂'s hydrogen storage capabilities. The MgH₂ composite with MnTiVZr-4 nanosheets demonstrated dehydrogenation at a lower temperature of 196.9 ℃, with the activation energy for dehydrogenation significantly reduced to 92.6±4.8 kJ·mol^-1. Besides, the composite showed rapid hydrogen absorption even at room temperature (25 ℃) and was capable of charging 5.2 wt% H₂ in just 10 min at 150 ℃. Meanwhile, the composite maintained stable hydrogen absorption and desorption over 60 cycles, with a final capacity of 6.1 wt%, indicating robust cycling performance. The enhanced performance, combined with the excellent cycling stability, positions this optimized MgH₂ composite as a promising material for practical hydrogen storage applications.
