Enhanced Stability of MFI Zeolite Membranes for Separation of Ethanol/Water by Eliminating Surface Si-OH Groups.
The practical application of pure-silica MFI zeolite membranes for ethanol/water separation by pervaporation is limited by its poor stability. Herein, we present the Si-OH eliminated MFI membranes by a simple dopamine modification, which can effectively prevent the chemical reaction between Si-OH groups and components, endowing the long-term pervaporation stability.
