Effect of Ti-Based Additives on the Hydrogen Storage Properties of MgH2: A Review

For the few past decades, study of new hydrogen storage materials has been captivating scientists worldwide. Magnesium hydride, MgH2, is considered one most promising due to its low cost, high capacity, reversibility and abundance Mg. However, it requires further research improve performance as some drawbacks such poor dehydrogenation kinetic, operational temperature, which limit practical application. In this study, we introduce an overview recent progress in improving MgH2 by addition titanium-based additives, are important groups additives. The role Ti-based additive hydrides, oxides, halides, carbides carbonitrides overviewed. addition, existing challenges future perspectives Mg-based hydrides also discussed.
