A hydrogen storage carbon material having a carbon structure suited for hydrogen storage and a production method thereof. The hydrogen storage carbon material according to this embodiment includes a carbon structure which has a ratio of an ultramicropore volume to a micropore volume of 60% or more, and in which stored hydrogen exhibits, inH-NMR measurement, a second peak at a position corresponding to a chemical shift of from &#x2212;2 ppm to &#x2212;20 ppm with respect to a first peak attributed to gaseous hydrogen.

Hydrogen storage carbon material

A carbon nanomaterial produced by: performing centrifugal melt spinning of core-shell particles that are prepared by using fine particles containing a carbon precursor polymer and a thermally decomposable polymer that disappears as a result of heat treatment, wherein the core-shell particles are heated up to a temperature at which phase separation thereof is not caused, and pressed against a plate-like heaterhaving a large number of poresA that penetrate therethrough in a thickness direction of the plate-like heater using centrifugal force; making the fiber obtained by the centrifugal melt spinning infusible; and performing carbonization thereof. According to this method, a carbon nanomaterial such as a carbon nanotube or a carbon nanofiber can be produced with high efficiency.
