Critical Factors in the Seed-Assisted Synthesis of Zeolite Beta and 'Green Beta' from OSDA-Free Na+-Aluminosilicate Gels...

摘要

Zeolites are crystalline microporous crystals composed of aluminosilicate frameworks and they have been widely used as catalysts, ion-exchangers, and adsorbents in many industrial fields. In general, the framework structures and chemical compositions (Si/AI ratio) of zeolites determine their pore characteristics (size and channel system), morphological features, and physicochemical properties. Zeolite beta is one of the most important zeolites because of its excellent properties and its unique pore structure.
