Effect of Carbonized 2-Methylnaphthalene on the Hydrogen Storage Performance of MgH2

“…New renewable energy is urgently needed to address the issues of the energy crisis and environmental pollution. − Among the possibilities, hydrogen energy stands out because of the key advantages of high energy density and net calorific value of combustion, abundant resources, and zero pollution, to name a few. − Yet, its large-scale utilization is limited by the lack of efficient and safe storage processes. − A metal hydride is one of the high-profile materials for hydrogen storage due to its high volumetric hydrogen storage capacity and excellent safety performance, − and it mainly works in the forms of metal alloys or compounds. , Currently, metal hydrogen storage materials can be divided into three categories: (1) binary hydrides MH x (M = main-group or transition metal, such as LiH, MgH 2 , and AlH 3 ), − (2) intermetallic hydrides AB x H y (A and B represent the hydrogenated and unhydrogenated metals, respectively, such as Mg 2 NiH 4 and Mg 2 FeH 6 ), − and (3) complex metal hydrides, MEH x (e.g. LiNH 2 , [BH 4 ] − , and [AlH 6 ] − ). − Among the above metallic hydrogen storage materials, Mg-based hydrogen storage materials have attracted intense interest due to their high hydrogen storage capacity (7.6 wt %) and low cost. ,, Nevertheless, the sluggish hydrogenation and dehydrogenation kinetics, relatively stable thermodynamics, and high initial decomposition temperature remain major problems. − …”
