Diffusion controlled hydrogen desorption reaction for the LiBH4/2LiNH2 system

Improved hydrogen desorption properties of Co-doped Li2BNH6

“…Fourier transformation of the XAFS spectra showed that the ball milled sample had a dominant peak at around 2.53 Å with a shoulder at 1.94 Å (Figure 7), which are close to the second shell Co-Co distance (2.67 Å) and the first shell Co-B distance (2.08 Å) of CoB, respectively [31]. As Tang et al [20] improve the dehydrogenation kinetics, as well as in the Co-doped dehydrogenation of NH 3 BH 3 and Li 3 BN 2 H 8 [32,33]. …”

Synthesis and crystal structure of a novel nitride hydride Sr2LiNH2

“…In order to improve the thermodynamic properties of binary Li-N-H system, Li was compositionally substituted by other elements, and several types of ternary or multinary metal-N-H systems (e.g. Li-Mg-N-H [5][6][7][8][9], Li-Ca-N-H [10,11], Li-Al-N-H [12][13][14], Li-B-N-H [12,15], Li-Co-N-H [16] and Li-Mg-Al-N-H [17,18]) were developed.…”

“…One is investigating the hydrogen absorption/desorption property [1][2][3][4][5][8][9][10][11][12][13][14][15][16][17][18]; the other is revealing the reaction mechanism involved in the hydrogen absorption/desorption processes [1,6,7,[14][15][16]21]. It was reported that the new ternary imides with mixed alkali and alkaline earth cations, Li 2 Mg(NH) 2 and Li 2 Ca(NH) 2 , were formed along with the dehydrogenation reaction in the Li-Mg-N-H and Li-Ca-N-H systems, respectively [5,8,11,[19][20][21].…”

Improved dehydrogenation performance of LiBH4/MgH2 composite with Pd nanoparticles addition

“…Among them LiBH 4 has quite high theoretical gravimetric (18.5 wt.%) and volumetric (121 g L −1 ) hydrogen storage capacities, potentially being a superior hydrogen storage material. However, the thermodynamic and kinetic limitations that are essentially imposed by the involved strong covalent and ionic bonds greatly restrain the practical applications of LiBH 4 [2,7,[14][15][16][17].…”
