“…For H 2 cryo‐adsorption, porous BN is comparable to most of the porous materials investigated so far . The question may arise as to whether BN is worth being investigated in comparison to cheaper and more easily prepared hosts such as carbonaceous or zeolitic supports.…”

Boron nitride, BN, for hydrogen storage emerged in the beginning of the millennium and there swiftly followed more than 15 years of efforts combining experimental laboratory works and to a greater extent computational predictions. BN has been considered mainly for the storage of molecular hydrogen, H2, by physisorption and/or chemisorption over a wide range of temperatures, that is, between −196 °C and 300 °C. Yet its potential has gone beyond the sorption of H2 as it has been also, although less extensively, involved in chemical H storage. The present review aims at giving a comprehensive overview of the main experimental results and findings as well as of the different avenues worth being explored. A key lesson of this survey is that boron nitride may turn out to be a promising material for hydrogen storage at room conditions provided all the predictions come true. The “ball” is now in the lab experimenters’ court.

“…Metal hydrides have been proven to be excellent alternatives for hydrogen storage, offering a high hydrogen storage capacity per unit volume, safety and reliability, as well as high purity of the supplied H 2 in comparison with hydrogen storage in a tank of compressed gas or liquid hydrogen . In the past decades, a huge variety of materials were tested as metal hydrides but only a few could really satisfy the desired hydrogen storage requirements for a system such as reversibility, high gravimetric storage capacity, low cost, and ability to work at low temperatures under moderate values of pressures …”

Body‐centered cubic (BCC) and high‐entropy alloys are being investigated as potential hydrogen storage materials due to their ability to absorb high amounts of hydrogen at moderate temperatures. Herein, the synthesis and hydrogen storage behavior of new MgVCr BCC and MgTiVCrFe high‐entropy alloys are studied. The alloys are initially synthesized by mechanical alloying via high‐energy ball milling (HEBM) under hydrogen atmosphere followed by high‐pressure torsion (HPT) processing to improve activation. X‐ray diffraction (XRD) in combination with transmission electron microscopy (TEM) shows a very refined nanostructure in both samples with the presence of a BCC solid solution phase for MgVCr, whereas the crystalline and amorphous phases coexist in MgTiVCrFe. The MgVCr alloy exhibits fast kinetics but with a low reversible hydrogen storage capacity (up to 0.9 wt%), whereas MgTiVCrFe shows low affinity to absorb hydrogen. Moreover, MgTiVCrFe demonstrates a partial decomposition from the initial structure by hydrogen storage cycling, whereas MgVcr exhibits reasonable stability.

Summary In this study, a strategy that optimizes the pore size to enhance the adsorbed H2 amount (at 298 K) is investigated. Pore size and ultramicropore fraction (ultramicropore volume/total pore volume) were controlled by Fe:TPA ratio. The highest H2 adsorption capacity of 0.47 wt% (298 K and 7.6 bar) belongs to MIL‐88B‐3, which is higher than those of reported metal‐organic frameworks (MOFs) (MIL‐100, MIL‐101 [Cr], HKUST‐1, MOF‐5, and ZIF‐8). The enhanced H2 sorption capacity (1.96 times) is a consequence of the high fraction (89%) and volume (0.22 cm3/g) of ultramicropores with pore diameters of 0.6 nm. Our results demonstrate that pore size, fraction, and volume of ultramicropores control the amount of H2 adsorbed also at 298 K. With the use of perturbation assisted nanofusion synthesis strategy that introduces textural pores to the pore structure, a Brunauer‐Emmett‐Teller (BET) surface area higher than those of reported MIL‐88Bs has been achieved, and a strategy to synthesize MOFs with enhanced H2 sorption capacities is suggested.
