There are extensive efforts underway worldwide to develop inexpensive and practical hydrogen storage materials for the implementation of a hydrogen-based energy economy. Metal hydrides are leading candidates for hydrogen storage applications because they are solid at room temperature and release hydrogen on demand when heated. HSM systems Inc. has developed a practical hydrogen storage system i...

Reversible hydrogen uptake and the metal/dielectric transition make Mg/MgH2 system a prime candidate for solid-state storage dynamic plasmonics. However, high dehydrogenation temperatures slow hamper broad applicability. One promising strategy to improve is formation of metastable γ-MgH2. A nanoparticle (NP) design, where γ-MgH2 forms intrinsically during hydrogenation presented mechanism based...

We have demonstrated an extremely facile procedure for the preparation of 1D porous Ni@C nanostructures by pyrolysis of Ni-based coordination polymer nanorods. The highly aligned Ni-based polymer nanorods were prepared using nitrilotriacetic acid (NTA) as a chelating agent by a one-step solvothermal approach. The obtained precursors are demonstrated to have a well-designed 1D nanostructure and ...

The global interest in MgH2 is due to the natural availability of Mg and its capacity retain hydrogen at a concentration up 7.60 wt.%. Despite appealing characteristics ease production on an industrial scale ambient temperature using reactive ball milling (RBM) technique, highly stable chemical with sluggish hydrogenation dehydrogenation rates below 300 °C. Among different methods used improve ...

We have synthesized a new metastable metal hydride with promising hydrogen storage properties. Body centered cubic (bcc) magnesium niobium hydride (Mg(0.75)Nb(0.25))H(2) possesses 4.5 wt% hydrogen gravimetric density, with 4 wt% being reversible. Volumetric hydrogen absorption measurements yield an enthalpy of hydride formation of -53 kJ mol(-1) H(2), which indicates a significant thermodynamic...
