Abstract:
Homogeneously dispersed bimetallic oxides in nanocrystalline or amorphous forms, of the type MAl2O4 (where M = Mg, Ca, Mn, Co, Fe, and Zn) were prepared from bimetallic oxo-bridged alkoxides [(RO)2Al–O–M–O–Al(OR)2], where the Al–O–M–O–Al bonds were not hydrolytically cleaved. This approach yields hydroxides [(HO)2Al–O–M–O–Al(OH)2] which, upon thermal dehydration, yield oxides [OAl–O–M–O–AlO], such that M is homogeneously dispersed with an empirical formula of MAl2O4. These materials were obtained in high surface area forms and were characterized by X-ray diffraction, electron microscopy, surface area analyses, and solid-state 27Al NMR. Comparative studies of the hydrolysis of alkoxo-bridged alkoxides yielded mixed metal oxide phases with lower surface areas.
