Abstract
Sustainable and energy-efficient molecular separation requires membranes with high gas permeability and selectivity. This work reports excellent CO
separation performance of self-standing and thin-film mixed matrix membranes (MMMs) fabricated by embedding 2D Ti
C
T
MXene nanosheets in Pebax-1657. The CO
/N
and CO
/H
separation performances of the free-standing membranes are above Robeson's upper bounds, and the performances of the thin-film composite (TFC) membranes are in the target area for cost-efficient CO
capture. Characterization and molecular dynamics simulation results suggest that the superior performances of the Pebax-Ti
C
T
membranes are due to the formation of hydrogen bonds between Ti
C
T
and Pebax chains, leading to the creation of the well-formed galleries of Ti
C
T
nanosheets in the hard segments of the Pebax. The interfacial interactions and selective Ti
C
T
nanochannels enable fast and selective CO
transport. Enhancement of the transport properties of Pebax-2533 and polyurethane when embedded with Ti
C
T
further supports these findings. The ease of fabrication and high separation performance of the new TFC membranes point to their great potential for energy-efficient CO
separation with the low cost of $29/ton separated CO
.
