摘要：
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 990 degrees C. After milling for 40 hours, the graphite became significantly more disordered, and the amount of hydrogen desorbed upon heating decreased.
