Hydrogen is the ultimate vector for a carbon-free, sustainable green-energy. While being the most promising candidate to serve this purpose, hydrogen inherits a series of characteristics making it particularly difficult to handle, store, transport and use in a safe manner. The researchers’ attention has thus shifted to storing hydrogen in its more manageable forms: the light metal hydrides and related derivatives (ammonia-borane, tetrahydridoborates/borohydrides, tetrahydridoaluminates/alanates or reactive hydride composites). Even then, the thermodynamic and kinetic behavior faces either too high energy barriers or sluggish kinetics (or both), and an efficient tool to overcome these issues is through nanoconfinement. Nanoconfined energy storage materials are the current state-of-the-art approach regarding hydrogen storage field, and the current review aims to summarize the most recent progress in this intriguing field. The latest reviews concerning H2 production and storage are discussed, and the shift from bulk to nanomaterials is described in the context of physical and chemical aspects of nanoconfinement effects in the obtained nanocomposites. The types of hosts used for hydrogen materials are divided in classes of substances, the mean of hydride inclusion in said hosts and the classes of hydrogen storage materials are presented with their most recent trends and future prospects.

“…A balancing and coupling between nanoconfinement and catalysis were recently focused on to improve the hydrogen sorption properties of NaAlH 4 . Li et al succeeded in a strategy to combine the confinement and catalysis (catalyzed sample denoted as NaAlH 4 /Raney Ni) to make possible NaAlH 4 desorption at nearly 100 • C [174]. The NaAlH 4 /Raney Ni desorbed H 2 at initial temperature 85 • C and finished at 260 • C with the lowest activation energy~20 kJ mol −1 .…”

The Catalytic Role of D-block Elements and Their Compounds for Improving Sorption Kinetics of Hydride Materials: A Review

et al. 2021

The goal of finding efficient and safe hydrogen storage material motivated researchers to develop several materials to fulfil the demand of the U.S. Department of Energy (DOE). In the past few years, several metal hydrides, complex hydrides such as borohydrides and alanates, have been researched and found efficient due to their high gravimetric and volumetric density. However, the development of these materials is still limited by their high thermodynamic stability and sluggish kinetics. One of the methods to improve the kinetics is to use catalysts. Among the known catalysts for this purpose, transition metals and their compounds are known as the leading contender. The present article reviews the d-block transition metals including Ni, Co, V, Ti, Fe and Nb as catalysts to boost up the kinetics of several hydride systems. Various binary and ternary metal oxides, halides and their combinations, porous structured hybrid designs and metal-based Mxenes have been discussed as catalysts to enhance the de/rehydrogenation kinetics and cycling performance of hydrogen storage systems.

NaAlH4 and LiAlH4 are promising materials for hydrogen storage due to their high hydrogen density (7.4 and 10.5 mass%, respectively). However, their practical application is hampered from the slow hydrogen kinetics and poor reversibility. To improve the hydrogen properties of alanates, the alternative core–shell strategy has been proposed. In this respect, a simple solvent evaporation method is presented to synthesize the alanate core. In this approach, NaAlH4 and LiAlH4 are stabilized by solvation and electrostatic forces, respectively, through the addition of ionic salts. Remarkably, it is found that the size of the alanate nanoparticles can be tuned by varying the concentration of the introduced ion. More importantly, the partial substitution of Na+ and Li+ with cations of higher electronegativity enables the release of hydrogen at much lower temperatures.
