Hydrogen, which is a new clean energy option for future energy systems possesses pioneering characteristics making it a desirable carbon-free energy carrier. Hydrogen storage plays a crucial role in initiating a hydrogen economy. Due to its low density, the storage of hydrogen in the gaseous and liquids states had several technical and economic challenges. Despite these traditional approaches, magnesium hydride (MgH2), which has high gravimetric and volumetric hydrogen density, offers an excellent potential option for utilizing hydrogen in automobiles and other electrical systems. In contrast to its attractive properties, MgH2 should be mechanically and chemically treated to reduce its high activation energy and enhance its modest hydrogen sorption/desorption kinetics. The present study aims to investigate the influence of doping mechanically-treated Mg metal with 5 wt% amorphous Zr2Cu abrasive nanopowders in improving its kinetics and cyclability behaviors. For the first time, solid-waste Mg, Zr, and Cu metals were utilized for preparing MgH2 and amorphous Zr2Cu alloy (catalytic agent), using hydrogen gas-reactive ball milling, and arc melting techniques, respectively. This new nanocomposite system revealed high-capacity hydrogen storage (6.6 wt%) with superior kinetics and extraordinary long cycle-life-time (1100 h) at 250 °C.

“…The particles with nano size possess abundant surface active sites for surface modification, and the greatest strength of Fe 3 O 4 @SiO 2 nanoparticles is their targeting ability. These magnetic particles can be attracted to a target zone under the action of an external magnetic field, which makes recovery feasible [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Moreover, the inert SiO 2 -shell can prevent the magnetic Fe 3 O 4 -core from oxidation, and the abundant surface hydroxyl of SiO 2 is highly conducive to surface grafting with organic ligands [ 22 , 23 , 24 , 25 ].…”

Fe3O4@SiO2 nanospheres with a core–shell structure were synthesized and functionalized with bis(2-pyridylmethyl)amine (BPMA). The photoresponses of the as-obtained Fe3O4@SiO2-BPMA for Cr3+, Cd2+, Hg2+ and Pb2+ ions were evaluated through irradiation with a 352 nm ultraviolet lamp, and Fe3O4@SiO2-BPMA exhibited remarkable fluorescence enhancement toward the Cd2+ ion. The adsorption experiments revealed that Fe3O4@SiO2-BPMA had rapid and effective adsorption toward the Cd2+ ion. The adsorption reaction was mostly complete within 30 min, the adsorption efficiency reached 99.3%, and the saturated adsorption amount was 342.5 mg/g based on Langmuir linear fitting. Moreover, Fe3O4@SiO2-BPMA displayed superparamagnetic properties with the saturated magnetization of 20.1 emu/g, and its strong magnetic sensitivity made separation simple and feasible. Our efforts in this work provide a potential magnetic functionalized nanosensor for naked-eye identification and adsorption toward the Cd2+ ion.

Mg‐based hydrogen storage materials have drawn considerable attention as the solution for hydrogen storage and transportation due to their high hydrogen storage density, low cost, and high safety characteristics. However, their practical applications are hindered by the high dehydrogenation temperatures, low equilibrium pressure, and sluggish hydrogenation and dehydrogenation (de/hydrogenation) rates. These functionalities are typically determined by the thermodynamic and kinetic properties of de/hydrogenation reactions. This review comprehensively discusses how the compositeization, catalysts, alloying, and nanofabrication strategies can improve the thermodynamic and kinetic performances of Mg‐based hydrogen storage materials. Since the introduction of various additives leads the samples being a multiple‐phases and elements system, prediction methods of hydrogen storage properties are simultaneously introduced. In the last part of this review, the advantages and disadvantages of each approach are discussed and a summary of the emergence of new materials and potential strategies for realizing lower‐cost preparation, lower operation temperature, and long‐cycle properties is provided.
