“…Also, a direct synthesis of the Ce-containing beta zeolite (23) and modification of MCM-41 with La (24,25), as well as MSU-X with La and Ce (26), have been reported. As demonstrated in (27) the addition of La 2 O 3 to AlMCM-41 improves its thermal stability. Recently, a mesoporous ceria has been prepared using a hybrid organic and inorganic route (28).…”

“…Precipitation routes are best suited to siliceous materials, which are thermally stable up to 800 8C. [10] Non-siliceous mesoporous materials are often more difficult to synthesize by precipitation routes and often exhibit poor crystallinity and low thermal stability. Methods of strengthening the mesostructured walls include increasing their thicknesses, [7] exchanging surface sulfate groups for other species such as phosphate in the case of mesostructured ZrO 2, [11] and using [Al 13 O 4 (OH) 24 (OH 2 ) 12 ] 7 + polycationic species as structural building blocks to form rigid Al 2 O 3 frameworks.…”

A general synthetic method for the preparation of nanostructured materials with large surface area was developed by using nanoparticle building blocks. The preparation route involves the self-assembly of functionalized nanoparticles in a liquid-crystal phase. These nanoparticles are functionalized by using difunctional amino acid species to provide suitable interactions with the template. Optimum interactions for self-assembly of the nanoparticles in the liquid-crystal phase were achieved with one -NH2 group anchored to the nanoparticle surface per 25 A(2). To maximize the surface area of these materials, the wall thicknesses are adjusted so that they are composed of a monolayer of nanoparticles. To form such materials, numerous parameters have to be controlled such as the relative volume fraction of the nanoparticles and the template and size matching between the hydrophilic component of the copolymer and nanoparticles. The surface functionalization renders our synthetic route independent of the nanoparticles and allows us to prepare a variety of nanostructured composite materials that consist of a juxtaposition of different discrete oxide nanoparticles. Examples of such materials include CeO2, ZrO2, and CeO2-Al(OH)3 composites.
