Despite previous reports on hetero-epitaxial growth, high-performance zeolite membranes have yet to be reported using this approach. Here, the successful hetero-epitaxial growth of highly siliceous ZSM-58 (DDR-type zeolite) films from a SSZ-13 (CHA-type zeolite) seed layer is reported. The resulting membranes show excellent CO2 perm-selectivities, having maximum CO2 /N-2 and CO2 /CH4 separation factors (SFs) as high as about 17 and 279, respectively, at 30 degrees C. Furthermore, the hybrid membrane maintains the CO2 perm-selectivity in the presence of water vapor (the third main component in both cases), that is, CO2 /N-2 SF of about 14 and CO2 /CH4 SF of about 78, respectively, at 50 degrees C (a representative temperature of both CO2-containing streams).
