| Outline of Final Research Achievements |
Near Infrared (NIR) spectroscopy revealed that (i) H2O clusters formed in alcohol solvents (ethanol or tert- butanol) have rigid hydrogen bond networks as compared to pure liquid H2O.; (ii) Hydroxyl, various organic functional (NH2, COOH, SO3H) groups and H2O adsorbed on SiO2-based adsorbents could be simultaneously analyzed. The interaction with H2O molecules could be summarized to be SiO2-NH2 (water-repellent) << SiO2 (hydrophobic) < SiO2-COOH (hydrophilic) < SiO2-SO3H (hydrophilic).; (iii) Aggregated H2O or methanol clusters having large H-bond networks (close to liquid phase) formed within the 3D pore of Y and beta zeolites. In contrast, less H-bonded clusters (close to vapor phase) formed within the cylinder-shaped pore of ZSM-5 and MOR zeolites.; (iv) NH3 and/or NH4+ adsorbed on Si-OH or H+ sites of zeolite surfaces could be simultaneously analyzed.
