The synthesis of nanostructured zeolites enables modification of catalytically relevant properties such as effective surface area and diffusion path length. Nanostructured zeolites may be synthesized either in alkaline media, and so contain significant numbers of hydrophilic silanol groups, or in
Mesoporous silica-aluminas as catalysts for the alkylation of aromatic hydrocarbons with olefins.
