Outline of Final Research Achievements

ZIF-8 synthesis in aqueous solution using non-ionic surfactant was carried out. Mono-dispersed ZIF-8 nanocrystal was successfully prepared by addition of non-ionic surfactant. Crystal size of ZIF-8 was decreased with increasing HLB (Hydrophilic Lipophilic Balance) value of non-ionic surfactant. In addition, ZIF-8 crystal could be also controlled by synthesis temperature. ZIF-8 adsorption property of hydrocarbon and alcohols were evaluated. Hydrocarbon and alcohol with smaller molecular size showed higher adsorption property. Diffusivity of n-hexane and 1-hexene within ZIF-8 crystal were measured. The diffusivity of n-hexane and 1-hexene were close each other regardless of unsaturated bond existence in diffusion molecule.
