Abstract
Two milling modes (shearing and impact) were applied to investigate the hydrogen storage properties of graphite. It was found that the shearing mode leads to 0.613 wt.% hydrogen absorbed in graphite, while impact mode leads to 2.718 wt.%. X-ray diffraction was used to investigate the structure of the as-milled and subsequent annealed samples. Differential scanning calorimetry was used to study thermally induced transformations in the as-milled samples. Infrared spectrometry was carried out to investigate the interaction between carbon and hydrogen atoms. Results are compared and discussed in conjunction with Laser desorption time-of-flight mass spectrometry results obtained earlier.
