Synthesis, structural characterization, and hydrogen desorption properties of Na[Al(NH 2 BH 3 ) 4 ]

In‐Situ and Real‐time Monitoring of Mechanochemical Preparation of Li2Mg(NH2BH3)4 and Na2Mg(NH2BH3)4 and Their Thermal Dehydrogenation

“…The observed exothermic processes occur at lower temperatures than those for pure AB and AB / MgH 2 mixture . In contrast to results of Nakagawa et al., who have observed three exothermic peaks at 53, 117, and 131 °C in AB / LiAlH 4 system, DSC analysis of DLMAB sample reveals two additional processes at 80 and 151 °C.…”

“…The endothermic reaction preceding thermal decomposition is characteristic for Na and Li amidoboranes . The weak endothermic DSC peak can be attributed to melting or amorphization of the mixture, eventually yielding species containing M(NH 3 ) + cations . Here the suggested synthetic route leads to formation of a Li‐containing system with DSC profile given in Figure .…”

Destabilization of Boron-Based Compounds for Hydrogen Storage in the Solid-State: Recent Advances

“…The latter was able to reabsorb 27% of the released hydrogen. However, a different group reported the emission of volatile byproducts (NH 3 , B 2 H 6 and B 3 H 6 N 3 ) during the decomposition of NaAl(AB) 4 [266].…”

Aluminum methylamidoborane complexes: mechanochemical synthesis, structure, stability, and reactive hydride composites

“…[15][16][17][18][19][20] However, it undergoes thermal decomposition in multiple steps at about 120 °C, 200 °C, and 500 °C, respectively, 16 accompanied by the evolution of some toxic volatile byproducts (B 2 H 6 , NH 3 , N 3 B 3 H 6 ) and severe foaming and volume expansion during the thermal decomposition. [21][22][23] Many strategies have been explored to overcome these problems; for example, by forming metal amidoboranes (MABs), 6,[24][25][26][27] including mono-metallic [28][29][30][31][32][33][34][35][36][37][38] and multi-metallic [39][40][41][42][43][44][45][46][47][48][49][50] derivatives. Compared to pristine AB, MABs oen have lower decomposition temperatures and/or release hydrogen with improved purity.…”
