Characterization and modification of waste magnesium chip utilized as an Mg-rich intermetallic composite

- Waste Mg chips (WMCs) were characterized in terms of potential use as a hydrogen storage medium.
- Mechanical milling, tetrahydrofuran and NaCl treatment were applied to modify the WMC surface.
- The obtained Mg-rich intermetallic composite exhibited a hydrogen storage capacity of 4.59 wt%.
