Abstract
This study presents the successful characterization and hydrolysis of
magnesium hydride (MgH2) for hydrogen generation. The as-received MgH2
served as a precursor in most of the hydrolysis experiments for H2 generation. The
phase-structural and morphological characteristics of the as-received MgH2 were
evaluated using scanning electron microscope (SEM), energy dispersive
spectroscopy (EDS) and X-ray dispersive diffraction (XRD) characterization
techniques. The hydrogen storage performance of the as-received MgH2 was
analysed by thermogravimetric analysis (TGA), differential scanning calorimetry
(DSC) and thermal desorption spectroscopy (TDS) techniques. The hydrolysis of
MgH2 was performed in a hydrogen generation reactor operated in a batch mode
where the temperature and H2 flow rate were logged.
