Dodecasil 3C, a pure silica zeolite with an MTN‐type structure, was prepared by liquid‐phase hydrothermal synthesis in the presence of the amino acid dl ‐histidine. This compound acts as a buffer and affects the growth of zeolite, in particular its aggregation behaviour and particle size. As a result of the alteration the amino acid exerts on the silica chemistry in aqueous solution, nucleation was lowered and dodecasil 3C was formed as large, single crystals with sizes up to 140 μm.(© Wiley‐VCH Verlag GmbH & Co.
