Recent progress of the effect of Co/Ni/Fe-based containing catalysts addition on hydrogen storage of Mg

Efficient storage technology (absorption and desorption) is the key to boom the application of hydrogen as energy storage media. Among the solid-state hydrogen storage materials, magnesium-based material exhibits many advantages and is considered one of the most promising materials. However, the disadvantages including poor hydrogen absorption, desorption kinetics and high operating temperature still need to be modified. The addition of catalysts is one of the optimal ways to improve the kinetic performance of MgH2. However, transition metal-based catalysts exhibit excellent catalytic performance. This work mainly summarizes the addition of Co/Ni/Fe-based catalysts on the hydrogen storage performances of Mg. While examining the differences in the performance of each catalyst, some future research perspectives are also illustrated.
