Modification of NaAlH4 properties using catalysts for solid-state hydrogen storage: A review

Magnesium-based hydrogen storage alloys have attracted significant attention as promising materials for solid-state hydrogen storage due to their high hydrogen storage capacity, abundant reserves, low cost, and reversibility. However, the widespread application of these alloys is hindered by several challenges, including slow hydrogen absorption/desorption kinetics, high thermodynamic stability of magnesium hydride, and limited cycle life. This comprehensive review provides an in-depth overview of the recent advances in magnesium-based hydrogen storage alloys, covering their fundamental properties, synthesis methods, modification strategies, hydrogen storage performance, and potential applications. The review discusses the thermodynamic and kinetic properties of magnesium-based alloys, as well as the effects of alloying, nanostructuring, and surface modification on their hydrogen storage performance. The hydrogen absorption/desorption properties of different magnesium-based alloy systems are compared, and the influence of various modification strategies on these properties is examined. The review also explores the potential applications of magnesium-based hydrogen storage alloys, including mobile and stationary hydrogen storage, rechargeable batteries, and thermal energy storage. Finally, the current challenges and future research directions in this field are discussed, highlighting the need for fundamental understanding of hydrogen storage mechanisms, development of novel alloy compositions, optimization of modification strategies, integration of magnesium-based alloys into hydrogen storage systems, and collaboration between academia and industry.

Cu₂ZnSnS₄ (CZTS), well-known for its use in photovoltaic and photocatalytic systems, has been studied as a solid-state hydrogen storage material. At 10 bar hydrogen pressure, structural and spectroscopic analysis revealed unambiguous lattice changes in the form of enhanced lattice parameters (a = 5.41 Å, c = 10.754 Å), a reduction in crystallite size from 66.37 nm to 56.70 nm. Raman and FTIR spectra confirmed hydrogen incorporation through vibrational mode changes and S–H stretching band emergence. A-mode near 336 cm⁻¹, including intensity changes and slight shifts, reflecting hydrogen-induced strain and defect interactions within the lattice. Through the emergence of an S–H stretching band around 2369 cm⁻¹, which was absent in the pristine sample. The material was observed with a high specific surface area, enhancing the adsorption kinetics for hydrogen. Storage capacity was 0.9 wt%, and the rate of desorption was 0.0108 m³/h at 200 °C. TGA demonstrated enhanced mass loss behavior in hydrogenated samples, suggesting modified thermal stability after hydrogen treatment. Gas chromatography analysis confirmed clean and selective hydrogen release. These findings make CZTS a low-cost and structurally versatile material with a promising reversible hydrogen storage solution in energy conversion applications.
