Carbon nanotubes grown on ZIF-L(Zn@Co) surface improved CO2 permeability of mixed matrix membranes

Jun Cheng et al.

Summary: Increasing CO2 permeability by tailoring CO2 diffusivity and selective absorption is crucial for efficient CO2 separation. By developing hierarchical structures composed of carbon nanotubes grown in-situ on carbonized ZIF-L (Zn@Co) (C-ZIF), high CO2 permeability mixed matrix membranes (MMMs) were fabricated. The hierarchically structured C-ZIF with nanotubes improved the gas diffusivity and provided abundant active sites for CO2 adsorption. MMMs with 10 wt% C-ZIF-700 showed significantly increased CO2 permeability (161.3 Barrer) and CO2/N2 selectivity (51.4), compared to pure Pebax membranes. This study demonstrates the great potential of carbonized-ZIF with hierarchical nanostructures in constructing high-performance MMMs for gas separations.

Removal of diclofenac sodium and cefixime from wastewater by polymeric PES mixed-matrix-membranes embedded with MIL101-OH/Chitosan

Jingjing Liu et al.

Summary: In this study, Mixed-Matrix-Membranes (MMMs) were used to remove residual active drug compounds in municipal effluents and pharmaceutical factory effluents. The addition of MOF modified with CS to PES membranes increased the number and size of micropores and porosity, leading to increased pure water flux and membrane permeability. The membrane's hydrophilicity and surface roughness also reduced membrane clogging, resulting in a higher flux recovery ratio and decreased irreversible fouling. Diclofenac sodium (DCF) was better separated than cefixime (CFX), and the performance of MMMs with MIL101-OH/CS was superior to MMMs with MIL101-OH, indicating that adding CS to MOF and PES membrane improved membrane performance to remove DCF and CFX.
