One-Pot Synthesis of High-Flux b-Oriented MFI Zeolite Membranes for Xe Recovery.
ACS Appl Mater Interfaces
October 2018
We demonstrate that b-oriented MFI (Mobil Five) zeolite membranes can be manufactured by in situ crystallization using an intermediate amorphous SiO layer. The improved in-plane growth by using a zeolite growth modifier leads to fusion of independent crystals and eliminates boundary gaps, giving good selectivity in the separation of CO/Xe mixtures. The fast diffusion of CO dominates the overall membrane selectivity toward the CO/Xe mixture.

Article Synopsis
- The study focuses on creating high-quality zeolite membranes with customizable chemical properties, which are necessary for improving their use in separation and catalysis.
- It details a method for directly attaching a b-oriented silicalite-1 layer to a commercial porous substrate, followed by a secondary growth process to produce ZSM-5 membranes with variable Si/Al compositions.
- The research also highlights the use of sodium to enhance crystal growth and reduce defects, leading to membranes that can switch between hydrophobic and hydrophilic characteristics, broadening their potential applications.
