Wan, Jingmeng;Nian, Mengjie;Yang, Chao;Ge, Kai;Liu, Junjie;Chen, Zhiquan;Duan, Jingui;Jin, Wanqin research published 《 Interface regulation of mixed matrix membranes by ultrathin MOF nanosheet for faster CO₂ transfer》, the research content is summarized as follows. Mixed matrix membranes (MMMs) incorporating porous materials received extensive attention for applications of gas separation, but the one shows significant high permeability and increased selectivity is rare. Here, we report a strategy of interface regulation in two groups of MMMs via formed H-bonding by a newly designed and ultrathin metal organic framework nanosheet (MOFN). The chem. stable MOFN (thickness: 5-8 nm) with lamellae of micrometre lateral dimensions was prepared from [Hf₆] cluster and tricarboxylate ligand, where the capping mol. of formic acid coordinates with Hf⁴⁺ ion as H-bonding donor toward incorporated polymers and also acts as an anisotropic regulator for MOFN growth. The well-distributed MOFN in two polymers shows sharply promoted CO₂ permeability (720 GPU and 2085 GPU), as well as enhanced separation factor, over wide pressure and temperature ranges that are suitable for CO₂ capture from natural gas. This is because the H-bonding regulated polymer-MOFN alignments lead to contractile channel and abundant porosity, validated by Raman mapping and positron annihilation lifetime spectroscopy. This work not only gives rise two candidate membranes for selective CO₂ removal from naturals gas, but also, more prospectively, deliveries a design philosophy for construction of advanced MMMs.

Voon, Boon Kee;Shen Lau, Hui;Liang, Can Zeng;Yong, Wai Fen research published 《 Functionalized two-dimensional g-C₃N₄ nanosheets in PIM-1 mixed matrix membranes for gas separation》, the research content is summarized as follows. The virtuous of two-dimensional (2D) nanomaterials in high aspect ratio and tunable surface functionality have geared towards their implementation in mixed matrix membranes (MMMs) for advanced gas separation In this study, the effects of functionalized 2D nanosheets in the MMMs for gas separation were investigated. The graphitic carbon nitride (g-C₃N₄) nanosheets were modified with various functional groups namely sulfuric acid group, aliphatic amino group, aromatic amino group, and sulfonic group via four different synthesis approaches. Polymers of intrinsic microporosity (PIMs, e.g., PIM-1) was selected as the continuous polymer phase due to its intrinsic high permeability and comparable selectivity towards different gas pair. The sulfonic acid functionalized g-C₃N₄ MMMs (e.g., PIM-1/g-C₃N₄-D) imparted high separation properties ascribed to the great CO₂ affinity induced by the sulfonic acid groups. In particular, PIM-1/g-C₃N₄-D (99:1) MMM demonstrated promising CO₂ separation performance, with CO₂ permeability of 3740 Barrer and CO₂/N₂ selectivity of 19.8. Moreover, at 5 wt% loading of g-C₃N₄-D, the H₂/N₂ and O₂/N₂separation of the MMMs had exceeded the 2008 Robeson upper bound, thanks to the periodic triangular ultramicropores in g-C₃N₄ that favor precise sieving of small gases. These results pave the way in using the developed membranes in practical H₂ purification, air separation and CO₂ capture.

In this study we self-assembled the four-armed porphyrin hetero dimer capsule Cap4, stabilized through amidinium-carboxylate salt bridges, in CH₂Cl₂ and CHCl₃. The dimer capsule Cap4 was kinetically and thermodynamically more stable than the corresponding two-armed dimer Cap2. The number of arms strongly influenced their recognition behavior; guests possessing small aromatic faces (e.g., 1,3,5-trinitrobenzene) preferred residing in the cavity of the two-armed capsule Cap2, rather than in Cap4, both thermodynamically and kinetically; in contrast, large aromatic guests (e.g., 9,10-dibromoanthracene) were encapsulated predominantly by Cap4 because of favorable entropic effects. The number of arms enabled self-sorting behavior of the dimer formation; complexation studies using an equimolar mixture of the four porphyrin constituents of the two capsules revealed the quant. formation of the corresponding dimers Cap2 and Cap4. Furthermore, we examined the specific mol. recognition of Cap2 and Cap4; NMR experiments of mixtures of Cap2 and Cap4 in the presence of favorable guests for Cap2 and Cap4 revealed that these guest mols. were encapsulated selectively by their preferred hosts.
