Abstract
This study presents the successful synthesis, characterization and hydrolysis of magnesium hydride (MgH2) and MgH2 based nanocomposites for hydrogen generation, storage and wastewater treatment. The as-delivered MgH2 serves as a precursor in most of the substrates synthesized for hydrogen production and storage in this study. In addition, Mg scrap was also investigated for the same purpose. The nanocomposites were prepared by means of a ball milling process in different time spans. MgH2, germanium (Ge), lithium aluminium hydride (LiAlH4), sodium aluminium hydride (NaAlH4), magnesium (Mg) scrap were the hydrogen generation/ storage substrates used in this study. The nanocomposites from the substrates were synthesized through ball milling of the powders in argon. The phase-structural and morphological characteristics of the composites were evaluated using transmission electron microscopy (TEM), selected area diffraction (SAD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray dispersive diffraction (XRD) characterization techniques...
