Outline of Final Research Achievements

We succeeded in synthesis of potassium (K) ion included -LIT type zeolite by the solvothermal reaction using a FAU-type zeolite and an ethanol solvent for the first time. In the -LIT type zeolite, the remarkable structural change by ion-exchange was found and its thermal stability was degraded considerably. These changes originate in a disappearance of the hydrogen bond contained in framework, which is the feature of -LIT type structure, and the pore-filling effect of K ion. Additionally, it was found that the -LIT zeolite containing K ions in nanopores is effective as a carbon combustion catalyst. Furthermore, the novel layered silicate Al-K-LDS including high aluminum content was synthesized by the solvothermal reaction using layered silicate RUB-18, and the mesoporous derivatives with low Si/Al ratio was also successfully prepared using Al-K-LDS. Obtained mesoporous derivatives showed high hydrophilic property, water resistance and high adsorption ability of enzyme (lysozyme).
