Outline of Final Research Achievements

Zinc containing zeolites are promising materials for ion-exchange and catalysis because of their unique ion-exchange capabilities for multivalent cataions and characteristic Lewis acidity. However, there have been several obstacles that prevent
zincosilicate zeolites from being synthesized rationally. In this work, several zeolites such as MOR-type, *BEA-type, MFI-type were synthesized using co-precipitation method. The obtained zeolites showed superior ion-exchange capacities and higher selectivity for multivalent cations compared with aluminosilicate analogues. CHA-type zincosilicate was also synthesized for the first time by optimizing the mixing order of raw materials.
