Sustainable NaAlH₄ production from recycled automotive Al alloy

Abstract

To reduce the carbon footprint associated with the production of hydrogen storage materials and to reduce their cost, we pursue the possibility of obtaining high-quality hydride-based materials from industrial metals...

Improvement in the Hydrogen Storage Properties of MgH2 by Adding NaAlH4

“…Complex hydrides such as LiBH 4 and NaAlH 4 have been studied by many researchers because they have high theoretical hydrogen storage capacities [1][2][3][4][5][6][7][8][9][10]. Many works were performed to improve the hydriding and dehydriding kinetics of Mg [11][12][13][14][15][16].…”

Tribochemically driven dehydrogenation of undoped sodium alanate under room temperature

“…[22][23][24] From the standpoint of mechanochemical phenomenology, there are certain similarities between alkali alanates and MgH 2 : both MgH 2 and NaAlH 4 are stable under mechanical milling 25 and can be formed by mechanochemical synthesis from metal precursors under a H 2 atmosphere. 26,27 Here, the question arises of whether NaAlH 4 is as susceptible to tribochemical dehydrogenation as MgH 2 is under similar conditions.…”

Bifunctional Ru‐Cluster‐Decorated Co3B−Co(OH)2 Hybrid Catalyst Synergistically Promotes NaBH4 Hydrolysis and Water Splitting

“…[14] Along with the same line, hydrogen-containing compounds, including formic acid (HCOOH), lithium aluminum hydride (NaAlH 4 ), and sodium borohydride (NaBH 4 ) have received significant attention owing to their high H 2 content, chemical stability and nontoxicity. [15] Among them, NaBH 4 is the best candidate. Nevertheless, the self-hydrolysis of NaBH 4 is restricted by the sluggish reaction kinetics.…”
