By reacting metal alkoxide precursors with surfactant molecules, the researcher was able to prepare ordered porous oxides of niobium, titanium, tantalum, and other transition metals. According to authors the pore size, crystallinity of the pore walls, and other materials properties are easily controlled by the synthesis method.
Using similar strategies but different starting materials, authors have synthesized porous, mixed-metal oxides such as WO3/ZrO2. To prepare the nanocomposites, authors used zirconia colloidal suspensions and triblock copolymers composed of ethylene oxide and propylene oxide as templating agents. The metal oxide nanocomposites are strong solid acid catalysts. Author asserted that in isooctane cracking comparisons, WO3/ZrO2 proved to be more resistant to deactivation by coking than USY, a commercial zeolite cracking catalyst.
