Ultramicroporous Materials and Membranes

RESEARCH TOPICS

Zeolites and Ceramic Nanotubes

We developed scalable wet deposition techniques that compatible with continuous process for the fabrication of zeolite/ceramic nanotube thin films. Specific research topics are described as follows. 

  • Zeolite membranes for pervaporation 

  • Zeolite-based antifog/antiglare coating 

  • Ceramic nanotube-based transparent electrode

Metal-Organic Framework (MOF)

Metal-organic frameworks (MOFs) are crystalline nanoporous materials. We identify promising ultramicroporous (d < 0.6 nm) MOFs for molecular separations, and study on the effects of framework flexibility on separation performance. We fabricate membranes for gas separation (CO2/N2, CO2/CH4, and H2/CO2) and pervaporation (alcohol dehydration and IPA purification).
