## Description

- description: Molecular hydrogen (H2) ortho-para conversion (O/P conversion) proceeds
    slowly at low temperatures accompanying a heat release. Thus, catalysts for accelerating
    this conversion rate are highly demanded in terms of the storage and utilization
    of liquid H2. The catalysts for this purpose are experimentally screened by examining
    a broad range of materials covering magnetic, non-magnetic, metallic, and nonmetallic
    oxides. The primary conclusions obtained are summarized below. (1) active materials
    are required to be non-metallic and to bear the cations with ionic radii smaller
    than the bond length of H2. (2) Metallic materials have almost no activity irrespective
    of with or without magnetism (3) The activity of materials belonging to (1) is
    largely enhanced when the constituting cation has a magnetic moment. In addition,
    there is a class of materials for which the activity is distinctly enhanced just
    upon substitution by the foreign ions.
