| Outline of Final Research Achievements |
Recently particular emphasis has been placed on the synthesis of nano-zeolites and their applications as acidic catalysts and/or in shape-selective catalysis, because zeolites with nanometer-sized particles allow greater diffusion of molecules and give easier access to internal pore sites, as a result of their high external surface area. In this project, a new method of nano-zeolite production by heating of a mixture of dry-milled zeolite and a small amount of NaOH solution, and as a result, highly crystalline zeolites of size 80 nm were obtained in mostly dry-process. The present method is more suitable for large-scale production than that using a dilute aluminosilicate solution for the recrystallization process, because its productivity per batch is much higher. These materials are good candidates for applications such as ion-exchangers, adsorbents, and seeds for thin films.
