Ball milling is an effective way of producing defective and nanostructured graphite. In this work, the hydrogen storage properties of graphite, ball-milled in a tungsten carbide milling pot under 3 bar hydrogen for various times (0-40 h), were investigated by TGA-Mass Spectrometry, XRD, SEM and Laser Diffraction Particle Size Analysis.

Graphite has been milled for up to 1000 h in a laboratory scale tumbling ball mill under vacuum. Raman spectroscopy of the powders indicated the increasing dominance of D-type graphitic sp2 bonding over G-type bonding with increasing milling time. Diamond-like sp3 bonding and possibly fullerene-like bonding also became evident after milling.

During ball milling, graphite can absorb a relatively large amount of hydrogen (7.4 wt %). However, during subsequent heating, hydrogen is usually desorbed together with a small amount of methane. Therefore, there is a need to understand the mechanism of hydrogen sorption. In this work, graphite samples were ball milled in a tungsten carbide pot under 3 bar hydrogen and then characterized by ...
