Surfactant-assisted synthesis of mesoporous zirconia powders with high surface areas
- Univ. of Nebraska, Lincoln, NE (United States); and others
Since the advent of mesoporous aluminosilicates (1), the possibility of producing similar structures with other metal oxides has attracted considerable attention. Stucky and coworkers (2) reported on the synthesis of tungsten, iron, and tin mesostructures, but attempts to remove the surfactant caused the pore structure to collapse. Antonelli and Ying (3) produced the first non-aluminosilicate-based mesoporous material that remained stable upon removal of the organic surfactant. They used tetradecylphosphate as the organic template and titanium isopropoxide partially substituted with acetylacetone as the metal source. Knowles and Hudson (4) recently showed that alkylammonium salts can be used to prepare zirconia in the mesoporous range, and they pointed out that the conventional mechanism of mesopore formation does not take place in this cationic surfactant-metal cation pair. 24 refs., 4 figs.
