"Two major species were identified in Fe-treated montmorillonite: monomeric or dimeric hydroxoaqua cations .Form II behaves similarly to hydrous ferric oxides, but its thermal crystallization to hematite is postponed to 500\u2013600 grad C. The Fe3+ cations in the interlayer space are much less thermally stable than Al pillars in pillared interlayered clays (PILCs). Form I is more active in oxidative dehydrogenation of propane, while form II is the active species in sorption of As and the non-specific combustion of propane. To produce only form II by the treatment of montmorillonite with Fe3+, its load must be kept below 20 wt. percent; otherwise the usual hydrous ferric oxides are formed." .
