A HYDROGEN INSERTION COMPOUND OF MOLYBDENUM OXIDE HYDRATE, H0.12-0.22MOO3 H2O, AND ITS FORMATION PROCESS FROM HYDROGEN MOLYBDENUM BRONZE, HXMOO3

Based on XRD and chemical analysis results, the hydrogen insertion compound of molybdenum oxide hydrate (H-hydrate) was suggested to be a genotypic compound of yellow molybdenum trioxide monohydrate, MoO3.H2O. H-hydrate was obtained in a hot HCl solution and in hot water from hydrogen molybdenum bronze, HxMoO3. The hydrogen bronze with x less-than-or-equal-to 0.24 and the molybdenum species formed in the solution played a role in the formation of H-hydrate. In this process, a temporary dissolution of Mo5+ was observed at the beginning of the formation.
