Nanostructured graphite was prepared by mechanical milling under hydrogen and argon atmospheres. The hydrogen concentration in the sample prepared by miling under hydrogen atmosphere reaches up to 7.4 mass% (CH0.95). Judging from the radial distribution function determined by the neutron diffraction measurement, there are two types of deuterium (hydrogen) coordinations. On the other hand, the hydrogen concentration does not exceed 0.5 mass% by the gas-phase hydrogenation for the sample prepared by milling under argon atmosphere.
