Abstract
A process of synthesizing synthetic manganese oxide hydrates having various structures including hollandite and todorokite structure by hydrothermal synthesis. The products have a high degree of crystallinity, and thermal stability.
Claims1
A synthetic manganese oxide octahedral molecular sieve OMS-1 whose tunnel structure is 3.times.3 and being thermally stable at about 500.degree. C., wherein said manganese oxide octahedral molecular sieve has an X-ray diffraction pattern essentially corresponding to FIGS. 2A to 2E when calcined at 100.degree., 200.degree., 300.degree., 400.degree.and 500.degree. C., respectively.
