摘要：

This paper deals with the study of the hydrogen output during the catalyzed radiolysis of water in the presence of the supramolocular compounds Fe2NiO(TMAc)(6).3HTMAc, FeCoO (TMAc)(6).3HTMAc, [Cr3O(C6COO)(6)] . ClO4, Fe3Ni2O(OH)(TMAc)(7)(Aacet)(3), Ni-2(H2O) (TMAc)(4)(HTMAc)(4), [Cr3O(TMAc).3H(2)O](TMAc), and Cr8F8(TMAc)(16). A Co-60 gamma-source of 5.1 x10(14) Bq activity at a rate dose of 8.038 kGy h(-1) was used. The radiolysis products were determined by mass spectrometry For a given irradiation tune, it was found that quantity of hydrogen obtained by water radiolysis is 6 - 18 times greater in the presence of the supramolecular compounds as catalysts than in their absence from the irradiated system.
