Magnesium is an attractive hydrogen storage candidate due to its high gravimetric and volumetric capacities (7.6 wt.% 110 gH2/l, respectively). Unfortunately, use as a material for hampered by the stability of hydride, dissociation temperature 573–673 K slow reaction kinetics. In order overcome those drawbacks, important advancement toward controlling enthalpy desorption temperatures nano-struc...

Abstract Reaction of a hexagonal planar palladium complex featuring [PdMg 3 H ] core with 2 is reversible and leads to the formation new 4 tetrahydride species alongside an equivalent magnesium hydride co‐product [MgH]. While reversibility this process prevented isolation ], analogous [PtMg [PtZn complexes could be isolated characterised through independent syntheses. Computational analysis (DF...

The hydridic character of octahedral metal hydride complexes of groups VI, VII and VIII has been systematically studied using molecular electrostatic potential (MESP) topography. The absolute minimum of MESP at the hydride ligand (Vmin) and the MESP value at the hydride nucleus (VH) are found to be very good measures of the hydridic character of the hydride ligand. The increasing/decreasing ele...

Highly crumpled graphene nanosheets (GNS) with a BET surface area as high as 1159 m(2) g(-1) was fabricated by a thermal exfoliation method. A systematic investigation was performed on the hydrogen sorption properties of MgH(2)-5 wt% GNS nanocomposites acquired by ball-milling. It was found that the as-synthesized GNS exhibited a superior catalytic effect on hydrogenation/dehydrogenation of MgH...

Reaction of PYR-(MgnBu)2, in which PYR is 2,6-[(DIPP)NC(Me)CHC(Me)N-]2-pyridine and DIPP is 2,6-iPr2-phenyl, with (DIPP)NH2BH3 gave PYR-[MgNH(DIPP)BH3]2 (56%) which was characterized by crystal structure determination. Addition of THF resulted in β-H elimination and formation of PYR-[MgNH(DIPP)BH3](MgH)·THF (57%), likewise characterized by crystal structure determination. Conversion of the seco...

The dissociative sticking probability for H2 on Pd films supported on sputtered Highly Ordered Pyrolytic Graphite (HOPG) has been derived from measurements of the rate of the H–D exchange reaction at 1 bar. The sticking probability for H2, S, is higher on Pd hydride than on Pd (a factor of 1.4 at 140 C), but the apparent desorption energy derived from S is the same on Pd and Pd hydride within t...
