Formation of Hierarchically Organized Zeolites by Sequential Intergrowth

Abstract

Make intergrowth, not war! Hierarchically organized MFI zeolites with micro-, meso-, and macroporosity (see scheme) in one structure were made by sequential intergrowth by using a simple organic structure-directing agent (OSDA) without meso- or macroporogens. The use of an OSDA that imperfectly fits the zeolite framework generated very thin zeolite plates with 90° rotational intergrowth.
