Under control : The synthesis of a MFI‐zeolite was effectively controlled and the zeolite length was minimized to 20 nm by adding alkyltriethoxysilane to the conventional hydrothermal synthesis. Owing to intracrystal mesopores and a large external surface area, the zeolite materials (see figure for examples) exhibited a remarkably enhanced catalytic activity for reactions involving large organic molecules, as compared to conventional MFI‐zeolites.
