We examined the effects of temperature, mixing ratio of a titania precursor (titanium oxysulfate acid hydrate; TiOSAH)/cationic surfactant (cetyltrimethylammonium bromide; CTAB) and gravity on the framework formation (hexagonal structure, pore size and wall thickness) and crystal growth of hexagonal-structured self-assemblies of nanocrystalline (anatase) titania templated by CTAB (Hex-ncTiO2/CTAB Nanoskeleton). In order to examine the effect of gravity on the framework formation and crystal growth of the Hex-ncTiO2/CTAB Nanoskeleton, the Hex-ncTiO2/CTAB Nanoskeleton was prepared under increased-gravity environments (generated with centrifuge). We found that growth of nanocrystalline titania in and/or on the Hex-ncTiO2/CTAB Nanoskeleton was enhanced with higher temperature, lower TiOSAH content and higher gravity. On the other hand, temperature, the TiOSAH/CTAB mixing ratio and gravity did not affect significantly the hexagonal-structure formation and pore size of the Hex-ncTiO2/CATB Nanoskeleton.
