In this study,the characterization and modification of waste magnesium chips(WMCs),which were produced by plastic molding in a gold manufacturing factory and are used as Mg-rich intermetallic composites in storing hydrogen,were discussed in detail.WMCs were analyzed using X-ray diffraction(XRD),X-ray fluorescence(XRF) spectroscopy,differential scanning calorimetry(DSC),scanning electron microscopy(SEM),and Brunauer-Emmett-Teller(BET) analysis to characterize the materials’ structural properties.Mechanical milling,organic treatment,and inorganic salt addition were carried out to modify the WMCs’ surface to prepare Mg-rich intermetallic composites for storing hydrogen.The modified samples were analyzed using high-pressure volumetric analyses to calculate their hydrogen storage capacity.The authors conclude that modified WMC was promising as an Mg-rich intermetallic composite that was suitable for use in hydrogen storage with a 4.59 wt%capacity at 320 C under a hydrogen pressure of 60 bar.
