Well-Organized Zeolite Nanocrystal Aggregates with Interconnected Hierarchically Micro—Meso—Macropore Systems Showing Enhanced Catalytic Performance.

Zeolite nanocrystal aggregates with interconnected hierarchically micro—meso—macroporous systems are prepared by a quasi solid state crystallization process from a mixture of dried amorphous meso—macroporous aluminosilicate gel and glycerol (autoclave, 130 °C, 1—2 d).
