主　　题：Waste magnesium chip Characterization Modification Hydrogen storage Intermetallic composite 

摘      要：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 *** 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 *** milling,organic treatment,and inorganic salt addition were carried out to modify the WMCs’ surface to prepare Mg-rich intermetallic composites for storing *** modified samples were analyzed using high-pressure volumetric analyses to calculate their hydrogen storage *** 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.
