Abstract

The hydrogen binding state in the mechanically milled graphite has been investigated by Raman scattering and infrared absorption. There is no C-H vibration signal in Raman scattering spectra, while, a C-H vibration signal has been clearly observed by infrared absorption. The dominant hydrogen configuration is C-H2 and the contribution of C-H3 slightly increases for a longer milling time. This result indicates the first experimental determination of the hydrogen state in the mechanically milled graphite under hydrogen gas atmosphere.
