Abstract

Ball milling is an effective way of producing defective and nanostructured graphite. In this work, graphite was milled under 3 bar hydrogen in a tungsten carbide milling pot, and the effect of milling conditions on the microstructure and hydrogen storage properties was investigated by TGA-Mass Spectrometry, XRD, SEM and Raman spectroscopy. After milling for 10 hours, 5.5 wt% hydrogen was released upon heating under argon to 990degC. After milling for 40 hours, the graphite became significantly more disordered, and the amount of hydrogen desorbed upon heating decreased.
