Fabrication of 3-(trihydroxysilyl)-1-propanesulfonic acid membranes with superior affinity and selectivity for NH3 permeation over H2 and N2 at 50–300 °C

Phenyl-incorporated polyorganosilica membranes with enhanced hydrothermal stability for H2/CO2 separation

“…5,6 However, inorganic substrates are often used in these membranes, making large-scale production a great challenge. 3,7–9…”
