The effect of alkaline earth metals (Magnesium and Calcium) on Hydrogen storage efficiency of alanate nanopowders
Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...
متن کاملSolubility of hydrogen in metals
Products of interactions of transition metals with hydrogen exhibit retentions of essential metallic properties accompanied by decreases of density. With reference to temperature and to hydrogen gas-pressures, p, in equilibrium, different metals exhibit very different levels of hydrogen content, c. For elements in subgroups 111, IV and V and palladium in group VIII, initial regions of solid sol...

متن کاملHydrogen storage in carbon nanotubes with Ni nanoparticles by electrochemical
In this paper, the electrochemical hydrogen storage in nanocomposite materials was studied. Multi-Walled Carbon Nanotubes (MWCNTs) electrode was prepared by mixing with special composite. The optimum ratio of MWCNTs was estimated 30-70% (w/w) in the composite material. MWCNTs were synthesized by Chemical vapor deposition (CVD). The nanocomposite was homogenized by microwave. Cyclic voltammetry ...
