To provide a method for manufacturing a hydrogen storage material of high purity in a high yield by a safe and simple process low in cost and reduced in environmental load, and the hydrogen storage material synthesized by this manufacturing method, highly controlled in structure, having lightweight properties, inexpensive and safe, high in transport properties and excellent in hydrogen storage capacity.
The method for manufacturing the hydrogen storage material has a process for applying low temperature heat treatment (100-300°C) to a polymer having a structure represented by formula (1) (wherein, R is a hydrocarbon group and may contain a hetero atom and n is 2-10,000) to form the hydrogen storage material comprising a fine crystal carbon material having a polycyclic aromatic hydrocarbon of a small unit. The hydrogen storage material is obtained using the polymer having the structure represented by the formula as a raw material to subject the same to low temperature treatment and comprises the fine crystal hydrocarbon having the polycyclic aromatic hydrocarbon of the small unit.
