 Abstract: The objective of this study was to synthesize mesoscopically ordered surfactant/cosurfactant templated metal oxides (silica, titania and zirconia). Hexadecyltrimethylammonium bromide was used as structure directing agent. 1-octanol was used as co- surfactant and trimethylbenzene was added to achieve a more swollen structure. Hexagonally ordered titanium- and zirconium- oxo, phosphates with d(100)-spacings of around 80 Angstrom were successfully derived. The silica materials reached d(100)- spacings of 50 Angstrom. The surfactant removal of the silica and titanium oxo phosphate materials succeeded with preservation of the hexagonal structure upon calcination, while the removal of the surfactants from zirconium oxo phosphate by thermal treatment was unsuccessful, and resulted in a collapsed structure. The materials were characterized by XRD and N-2- Sorption.
