A constellation of technologies have been researched with an eye towards enabling a hydrogen economy. Within the research fields of hydrogen production, storage, and utilization in fuel cells, various classes of materials have been developed targeting higher efficiencies and utility. This Review examines recent progress in these research fields from the years 2011-2021, exploring the concepts and materials directions important to each. Particular attention has been given to catalyst materials enabling the green production of hydrogen from water, chemical and physical storage systems, and materials used in technical capacities within fuel cells. Quantification of publication and materials trends provides a picture of the current state of development within each node of the hydrogen economy.

Nanomaterials have attracted great interest in recent years because of the unusual mechanical, electrical, electronic, optical, magnetic and surface properties. The high surface/volume ratio of these materials has significant implications with respect to energy storage. Both the high surface area and the opportunity for nanomaterial consolidation are key attributes of this new class of materials for hydrogen storage devices. Nanostructured systems including carbon nanotubes, nano-magnesium based hydrides, complex hydride/carbon nanocomposites, boron nitride nanotubes,TiS2/MoS2nanotubes, alanates, polymer nanocomposites, and metal organic frameworks are considered to be potential candidates for storing large quantities of hydrogen. Recent investigations have shown that nanoscale materials may offer advantages if certain physical and chemical effects related to the nanoscale can be used efficiently. The present review focuses the application of nanostructured materials for storing atomic or molecular hydrogen. The synergistic effects of nanocrystalinity and nanocatalyst doping on the metal or complex hydrides for improving the thermodynamics and hydrogen reaction kinetics are discussed. In addition, various carbonaceous nanomaterials and novel sorbent systems (e.g. carbon nanotubes, fullerenes, nanofibers, polyaniline nanospheres and metal organic frameworks etc.) and their hydrogen storage characteristics are outlined.

“…Improvement of the storage behavior of MgH 2 has been investigated using several catalysts, including elemental [6][7][8][9][10], intermetallic [11][12][13][14], oxide [5,[15][16][17][18], halide [19][20][21][22], hydride [23][24][25] and other additives [26,27]. Among the oxide catalysts, TiO 2 is known to be remarkable.…”

The high desorption temperature and slow desorption kinetics of MgH 2 makes it less competitive for future mobile applications; using a catalyst accompanied by mechanical milling seems to be a good solution to overcome those problems. Therefore, the addition of TiO 2 and NiO to MgH 2 accompanied by 15 h of mechanical milling was considered in this study. The phase constituent and hydrogen desorption of the powder mixture were investigated using X-ray diffraction (XRD) and a Sieverttype apparatus, respectively. XRD results showed that after milling, no binary or ternary compounds were formed, but hydrogen desorption time decreased and the desorbed hydrogen content increased. It seems that the increase in desorbed hydrogen was related to the simultaneous catalytic effect of TiO 2 and NiO as well as mechanical milling. The results showed that the addition of both catalysts can improve the hydrogen desorption behavior of MgH 2based nanocomposite compared to the addition of only one catalyst of the same amount.
