Cover Story: Pore channels in silica-based membranes with pore sizes in the range of several angstroms, can act as a molecular sieve to separate gas mixtures of different molecular diameters. For instance, helium and hydrogen with molecular diameters smaller than their pore size could permeate across the silica-based membrane, while gases with larger molecular diameters, such as argon or carbon dioxide, fail to permeate through the membrane. Therefore, pore size is of great importance for silica-based membranes. In this paper, we have developed a method which employs the experimental activation energy of gas permeation to estimate pore size distribution. View this paper.
