Phase transition and hydrogen storage properties of Mg17Ba2 compound

First-Principles Study on Hydrogen Storage Performance of Transition Metal-Doped Zeolite Template Carbon

“…Due to the great specific surface area and exceedingly uniform microporous structure, the zeolites template carbon (ZTC) nanostructures could render high capacity for absorbing hydrogen [11,12]. Furthermore, the intrinsic cation distribution in zeolites makes it feasible to improve hydrogen storage capability by decorating metal atoms in ZTC, to meet the technical requirements of safe and reliable hydrogen storage with small volume, lightweight, low cost and low density [13,14]. Recently, the density functional (DFT) study on hydrogen storage of lithium modified ZTC has been reported in high interest, in which the lithium atoms are utilized to modify the convex surface of ZTC carbon nanostructures so that this doping structure can be efficiently used as a hydrogen storage medium [15].…”

Microstructure and hydrogen storage kinetics of Mg89RE11 (RE = Pr, Nd, Sm) binary alloys

“…[24][25][26][27][28][29] Therefore, the addition of rare earth elements into Mg-based alloys as alloying elements shed light on the better hydrogen storage properties for alloys. The hydrogen storage capacity of La 2 Mg 17 reaches 6 wt% at the temperature of 350 C. 30 The Mg 3 La compound prepared by induction melting can absorb 2.89 wt% of hydrogen reversibly at 296 C. 31 Wu et al 32 investigated the hydrogen storage properties and phase transitions of Mg 17 Ba 2 , which has reversible hydrogen capacity of 4.0 wt% H 2 . Ma et al 33,34 proposed the addition of Ni to the CaMg 2 -based alloys resulted in room-temperature hydrogen absorption without an activation process, and a maximum hydrogen-absorption capacity of 5.65 wt%.…”

A Critical Review of Mg-Based Hydrogen Storage Materials Processed by Equal Channel Angular Pressing

“…Hydrogen fuel, a new kind of renewable and clean energy, has been considered as a promising candidate for an environmentally friendly source of alternative energy to the conventional fossil fuels in meeting the world's demand [3][4][5]. Technical issues, for instance hydrogen storage, must be overcome before its utilization in large-scale applications.…”

“…For many years, metal hydride has attracted attention worldwide for its safe, cost-effective properties compared with other storage options such as high pressure gas tanks and cryogenic liquid, and it has already become a hot topic in the field of hydrogen storage. Numerous investigations have focused on Mg and its alloys, primarily due to their high hydrogen storage capacity, relatively low cost, and large abundance in the Earth's crust [4,5].…”
