| Outline of Final Research Achievements |
A novel concept of Molecular-Net-Sieving (MNS) where space consisting of networks can separate molecules based on the molecular sieving mechanism is proposed for the development of extremely high H2 permeable membranes. New silicon-based alkoxides and oligomers were prepared, and positron annihilation spectroscopy was applied to evaluate the pore structures. In addition, Molecular-Net-Sieving membranes were prepared from various types of precursors and characterized. Molecular-Net-Sieving membranes were confirmed to show higher hydrogen permeance higher than 1x10-6 mol m-2 Pa-1 s-1, and high separation factors for H2/propane (>1,000) and H2/SF6 (>10,000).
