Center for the Study of Matter at Extreme Conditions, Department of Mechanical and Materials Engineering, Florida, International University, Miami, FL 33199, USA, High-pressure study of ammonia borane started after the, material was recognized for its high potential for hydrogen, this molecular crystal with weak intermolecular interac-, tions introduces a range of changes in atomic bonding and, in turn produces crystal structure transitions. We have studied the phase transformation behavior of the potential hydrogen storage compound ammonia borane at low temperature (from room temperature down to 90 K) and high pressure (from ambient pressure to 9.5 GPa at room temperature and up to 15 GPa at 90 K) region using the diamond anvil cell. The incorporation of AB into the LiBH 4 structure intrinsically increases the cell volume and decreases the volume density of Li ion, which substantially facilitates the Li-ion conduction. While much work is still needed to comprehensively understand the pressure influence on this molecular crystal, a phase diagram based on the available experimental and theoretical data is constructed. J Am Chem Soc 128:12048–12049, ammonia-borane by iridium dihydrogen pincer complex differs, from ethane dehydrogenation. Note that for readability purposes, only the pictograms, signal words and hazard statements referred in more than 5% of the notifications under CLP are displayed. To obtain graphene from mineral coal for technological aplications. Chem Eur J 17:6043–6047, borane catalyzed by aminophosphine-stabilized precursors of, rhodium nanoparticles: ligand effects and solvent-controlled, product formation. Direct transfer hydrogenation of imines was observed with ammonia–borane, which proceeded under mild conditions without the help of a catalyst. orthorhombic structure for this phase, but all later studies, cated that the unit cell consists of two ammonia borane, hydrogen atoms were disordered in the structure. redistribute this material, requesters must process their own requests via the RightsLink permission Chen J, Couvy H, Liu H et al (2010) In situ X-ray study of, ammonia borane at high pressures. Influence of pressure on ammonia borane has been exten-, sively studied in the past decade. their DFT calculation and XRD study. One possible source of this hydrogen that has been studied is a… AKOS015914235. I-VI indicated six distinct crystal structures. study proposed that the disordered hydrogen atoms likely, occupy 12 sites around each of the boron and nitrogen, that a high-order rotation about the B–N bond was, required for hydrogen atoms presenting possibilities for, 12-site model. The, and 37 GPa, respectively, with the pressure derivative of, values of the bulk moduli reported by Lin et al. Here you can find all of the regulations and regulatory lists in which this substance appears, according to the data available to ECHA. This information has not been reviewed or verified by ECHA, and may change without prior notice. We provide evidence to suggest that in all cases, the stabilizing dihydrogen bonds arise from charge transfer between orbitals of the general \(\sigma _{\mathrm{B-H}}\rightarrow \sigma ^*_{\mathrm{N-H}}\) type. Appl Phys Lett 92:091916, 82. Paolone A, Palumbo O, Rispoli P et al (2009) Absence of the, structural phase transition in ammonia borane dispersed in mes-. oporous silica: evidence of novel thermodynamic properties. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9.
