Ti-doped LiAlH4 for hydrogen storage: Rehydrogenation process, reaction conditions and microstructure evolution during cycling

Synthesis of LiAlH4 Nanoparticles Leading to a Single Hydrogen Release Step upon Ti Coating

“…Nanosized LiAlH 4 modified with Ti almost fully decomposed through a single and extremely exothermic event recorded by DSC at 120 • C (Figure 6a,b). In comparison, bulk LiAlH 4 ball milled with TiCl 3 (material denoted bulk-LiAlH 4 /Ti) decomposed following the known decomposition path of LiAlH 4 -i.e., via Steps 1 and 2 (Figure 6c,d)-in agreement with previous reports [9,43,44]. This was confirmed by the XRD of bulk LiAlH 4 /Ti after heating at 150, 200 and 300 • C.…”

Enhanced hydrogen storage properties of LiAlH4 catalyzed by CoFe2O4 nanoparticles

“…28,35,44,50 However, the rehydrogenation property was not ideal. From the practical applications perspective, solid-state materials (LiAlH 4 , NaAlH 4 , MgH 2 , etc.)…”

Effect of Al on the hydrogen storage properties of Mg(BH4)2

“…2(a). It can be seen that the pure LiAlH 4 shows a two-step desorption, corresponding to reactions (2) and (3), respectively [14]. It can be observed that Mg(BH 4 ) 2 exhibits a two-step desorption.…”

“…As a good resource of Al, LiAlH 4 shows an accessible hydrogen storage capacity of 7.9 wt.% when decomposed to LiH, Al and H 2 at moderate temperatures in a two-step dehydrogenation process (Eqs. (2) and (3)) [14]. Reference [13] reported that LiAlH 4 provides homogenous dispersion of Al and LiH at the surface of the LiBH 4 particles.…”
