Abstract ：
Organic solvent nanofiltration (OSN) is an emerging membrane-based technology for molecular separation. The design and fabrication of membranes with unique structures are important to obtain high performance. Herein, ZIF-8 nanoparticles are grown in situ on the surface of graphene oxide (GO) nanosheets and then assembled on a tubular ceramic substrate through a vacuum-assisted assembly method. ZIF-8 anchored on the GO nanosheets is evolved into ZnS polyhedra with a hollow structure through in situ sulfurization. The formed ZnS@GO membrane is composed of a layered structure of GO with the interlayer intercalated by ZnS hollow polyhedra and demonstrates high permeance for organic solvents. Compared to that of the ZIF-8@GO membrane, the permeance of the ZnS@GO membrane is enhanced by 4.4-fold when separating dyes from methanol, indicating their promising potential in the application of organic solvent nanofiltration.

Abstract ：
Building up selective mass transfer channels in polymeric membranes is a promising strategy to fabricate effective separation membranes. Herein, a thioether-functionalized hydrazone-linked covalent organic framework, COF-LZU8, pre-modified by Ag ion, was incorporated for constructing aromatic selective channels within a commercial poly (ether-block amide) (Pebax 2533) membrane. The inside nanochannels of resulting membrane were effectively confirmed by measuring the affinity and the selective free volume to toluene via quartz crystal microbalance and low-field nuclear magnetic resonance. Owing to the selective channels, the Ag-COF-LZU8/Pebax membrane presented a considerably enhanced performance for toluene/n-heptane separation comparing with pristine Pebax membranes. The optimized membrane could perform a permeation flux of 293 g/m(2)h and a separation factor of 4.03 for the separation of 50 wt% toluene/n-heptane mixture.

Abstract ：
A defect-free, robust and selective barrier is essential for manufacturing membranes with targeted high permeability and selectivity. Here we report a new route to engineering a separation composite membrane by confining both channels in nanoscale metal organic frameworks (MOFs) and charges in a polyelectrolyte in the inner space of a porous supportviaa counter-diffusion method. A simple thermal annealing treatment of the interface between the MOF, polymer and support favorably reduced voids inside this nano-confinement environment. As this composite membrane combines both the support and barrier as one, it minimizes mass transfer resistance of water molecules. In a separation test, it readily achieved the state-of-the-art permeance. This simple chemical approach to upgrade membrane structures will offer wide opportunities in separation devices.

Abstract ：
Organic solvent nanofiltration (OSN) is emerging as an efficient and emerging approach for separation and purification of solute from organic solvents, which however were severely underdeveloped because of the low permeance of membranes. Herein, a novel mixed matrix membrane (MMM) was developed by incorporation of modified mesoporous silica nanoparticle (MSN) into commercially-available polydimethylsiloxane (PDMS) matrix for removal of trace impurities, such as Evans blue or vitamin B12, from different organic solvents. Notably, because of the designed nanoscale spaces originated from MSN, the permeance of the optimized MMM reached up to 31.2 L m(-2).h(-1).MPa-1, around 17-fold enhancement compared with that of pristine PDMS membrane. Low-field nuclear magnetic resonance was employed to trace the solvent state in the MMM. The MMM exhibited high MeOH absorption capability but low-swelling attribute, certificating the high permeance and long-term stability of the MMM. The MMM was stably tested in MeOH solution for more than 80 h, indicating the great promise for future practical OSN applications.

Abstract ：
Recovery of butanol is a potential biofuel production process, which can be achieved through membrane separation technology. In this study, Zeolitic Imidazolate Framework-8 (ZIF-8) modified graphene oxide (ZGO) with polyether block amide (PEBA) was deposited on ceramic tubular substrate to prepare composite membrane for bio-butanol recovery. ZGO laminates can be used to form transport channels for butanol molecules to enhance the permeance. The affinity of laminate to butanol was improved because of the hydrophobic ZIF-8 particles. Therefore, the separation performance of ZGO/PEBA membrane was enhanced. The microstructure and chemical property of the ZGO/PEBA membranes were characterized. Different preparation and operation conditions were also investigated to optimize the separation performance. Moreover, ZGO/PEBA composite membranes were evaluated in model acetone-butanol-ethanol (ABE) solution, which also exhibited high butanol recovery performance. Therefore, this facile strategy may provide a potential application in the commercialized ABE fermentation process.
