Hou, Rujing;Smith, Stefan J. D.;Konstas, Kristina;Doherty, Cara M.;Easton, Christopher D.;Park, Jaesung;Yoon, Heewook;Wang, Huanting;Freeman, Benny D.;Hill, Matthew R. research published 《 Synergistically improved PIM-1 membrane gas separation performance by PAF-1 incorporation and UV irradiation》, the research content is summarized as follows. Super-glassy polymer membranes have suffered from the trade-off relationship between permeability and selectivity for gas separation applications, despite the fact that membrane technol. exhibits remarkable energy efficiency advantages over other separation methods. Polymers of intrinsic microporosity such as PIM-1 offer high fractional free volume (FFV) and intermediate gas selectivity, with permeability several orders of magnitude higher than conventional glassy polymers. The methods of producing mixed matrix membranes (MMM) by incorporating nanoparticles into a polymer matrix, or crosslinking, have been widely studied to improve membrane selectivity. While crosslinking and nanoparticle incorporation often increase selectivity or permeability, resp., this is typically at the expense of the other, limiting transport properties to the Robeson upper bound. Porous aromatic frameworks such as PAF-1 have been shown to significantly increase the permeability of PIM membranes. Here, this nanoparticle additive is coupled with post UV irradiation treatment resulting in a membrane with both significantly improved membrane selectivity (i.e., 16-fold improvement for H₂/CH₄ selectivity, from 5.4 to 90) and high permeability (i.e., P(H₂) = 4800 Barrer). Characterization of the dual-enhanced membrane revealed that the synergetic performance is caused by a combination of the selective skin layer formed upon UV photo-oxidation with the addnl. permeable gas transport channels introduced to the bulk matrix by PAF-1. As a result of this dual-approach to membrane enhancement, the PIM-1 MMM exhibited better gas separation performance, surpassing the 2015 upper bounds for H₂/N₂ and H₂/CH₄ as well as 2008 upper bounds for H₂/CO₂ and CO₂/CH₄. Aging studies confirmed that PAF-1 addition, UV irradiation, and both modifications slowed phys. aging rate compared to the pure PIM-1 membrane. The performance of this membrane was also investigated at a range of thicknesses, revealing its potential as a candidate for other membrane forms at scale.

Hu, Mingming;Liu, Junjie;Kong, Jingjing;Jia, Peiyu;Qi, Ning;Wu, Yichu;Chen, Zhiquan;Xu, Shan;Li, Nanwen research published 《 Free volume and gas transport properties of hydrolyzed polymer of intrinsic microporosity (PIM-1) membrane studied by positron annihilation spectroscopy》, the research content is summarized as follows. In this work, a series of hydrolyzed polymers of intrinsic microporosity (PIMs) membranes were successfully synthesized under alk. conditions. Positron annihilation lifetime measurement is employed to analyze the pore structure of the hydrolyzed PIMs. In the original PIM-1, there are two kinds of pores, i.e. micropores with radius of 4.32 Å and ultramicropores with radius of 2.58 Å. The size of all the pores shows a continuous decrease with increasing hydrolysis time, which is confirmed by the reduced chain-to-chain spacing in the hydrolyzed PIMs measured by X-ray diffraction. Meanwhile, the fractional free volume also shows decrease after the hydrolysis process, while the relative number of ultramicropores increases. Benefiting from the smaller pore size in the hydrolyzed PIMs membrane, the gas mols. with smaller size (such as CO₂) can be separated more efficiently. The selectivity of CO₂/CH₄ of hydrolyzed PIMs reaches up to 30.05 with a relatively high CO₂ permeability of 140.58 Barrer, which exceeds the Robeson’s 1991 upper bound. Our results indicate that the hydrolyzed polymers of intrinsic microporosity membranes are promising candidates for gas separation membrane in the future.

Huang, Lingqi;Xiang, Yang;Luo, Mingwu;Zhang, Qi;Zhu, He;Shi, Kaiyuan;Zhu, Shiping research published 《 Hierarchically porous carbon with heteroatom doping for the application of Zn-ion capacitors》, the research content is summarized as follows. Zinc-ion capacitors (ZICs) are newly emerged hybrid devices consisting of battery-type anodes and capacitive-type cathodes, which are expected to meet high energy-power demands. The performance of ZICs is usually limited by the poor performance of porous carbon cathodes. In this work, heteroatom doped, hierarchically porous carbons were developed using a straightforward and scalable one-step method. The sp. surface areas and pore size distributions could be tailored by adjusting the precursor ratio and their effects on the electrochem. performance were investigated. The fabricated ZICs showed the highest capacity of 168.4 mAh g^-1 with an energy d. of 131.9 Wh kg^-1 at 0.5 A g^-1. The highest power d. of 30.8 kW kg^-1 could be achieved at 40 A g-1, allowing a fast complete discharging of a ZIC device in 6.6 s. Furthermore, the cycling stability of the device was investigated, registering nearly 100% capacity retention and almost 100% Coulombic efficiency after 12,000 cycles at 10 A g^-1. The morphol. and impedance tests measured at different charge and discharge conditions shed some light on the mechanism of the hybrid capacitive behavior. The proposed carbon cathodes offer great potential for ZICs in energy storage applications.

Huang, Lingqi;Luo, Zhiyong;Han, Wenjie;Zhang, Qi;Zhu, He;Zhu, Shiping research published 《 Direct transformation of ZIF-8 into hollow porous carbons and hollow carbon composites》, the research content is summarized as follows. Hollow porous carbons (HPCs) are a class of porous materials with advantages of high surface to volume ratio, large interior cavities, low d., and short diffusion length, which are promising in various applications. Direct carbonization of carbon precursors is the simplest and the most cost-effective method to prepare porous carbons, however, it often leads to non-hollow structures. Herein, we demonstrate the preparation of HPCs through a direct carbonization method with a two-step heating process of zeolitic imidazolate framework-8 (ZIF-8) and tetrafluoroterephthalonitrile (TFTPN). During the carbonization, ZIF-8 nanoparticles first react with TFTPN at low temperature to create polymer coatings on the surface, which are then converted into HPCs at elevated temperature The obtained HPCs show hierarchically porous structure with high sp. surface areas and pore volumes Addnl., this method has been adopted to fabricate Au@HPCs yolk-shell composites, exhibiting good catalytic performance in nitrobenzene reduction The developed synthesis strategy can enrich the toolbox for the preparation of novel HPCs and their composites.

Huang, Menghui;Lu, Kuan;Wang, Zhenggong;Bi, Xiangyu;Zhang, Yatao;Jin, Jian research published 《 Thermally Cross-Linked Amidoxime-Functionalized Polymers of Intrinsic Microporosity Membranes for Highly Selective Hydrogen Separation》, the research content is summarized as follows. Hydrogen is a vital and clean energy source, and it is of great significance to achieve efficient separation and purification of hydrogen. In this study, highly selective hydrogen separation was achieved by thermal crosslinking of amidoxime-functionalized polymers of intrinsic microporosity (AOPIM-1) membranes under an argon atm., where a two-step self-crosslinking reaction occurred among the amidoxime groups on the polymer chains by forming oxadiazole rings and triazine rings. The crosslinking reaction was systematically verified by ¹³C solid-state NMR, attenuated total reflection IR spectroscopy, and X-ray photoelectron spectrometry. Thanks to the controllable crosslinking reaction, not only are the gas transport channels finely tailored, but also the backbone structure is effectively retained. The resulting membranes exhibited remarkable mol. sieving behavior. The selectivities of H₂/CO₂, H₂/N₂, and H₂/CH₄ gas pairs are 16, 500, and 1000, resp., and the permeabilities of H₂, CO₂, N₂, and CH₄ are 300, 18.6, 0.6, and 0.3 Barrer, resp., far exceeding the state-of-the-art reported upper bound.

Huang, Menghui;Wang, Zhenggong;Lu, Kuan;Fang, Wangxi;Bi, Xiangyu;Zhang, Yatao;Jin, Jian research published 《 In-situ generation of polymer molecular sieves in polymer membranes for highly selective gas separation》, the research content is summarized as follows. Mol. sieve materials (MSMs) are regarded as ideal fillers for the fabrication of mixed matrix membranes (MMMs). However, the preparation of MSMs-based MMMs usually involves phys. mixing of insoluble filler and polymer matrix, which inevitably leads to filler agglomeration and two-phase incompatibility especially for high filler loading. Herein, we report a new strategy to construct MMMs through generating polymer mol. sieve (PMS) fillers in-situ in a thermally stable polymer matrix by post heating treatment. The in-situ generated PMS-based MMMs (i-PMS MMMs) possess greatly improved interfacial compatibility between matrix and filler and the effective loading content of PMS filler can reach as high as 70 wt%. The mol. sieving property of PMS endows the i-PMS MMMs with high gas selectivity of 183.0 for H₂/CH₄ and 128.9 for H₂/N₂, approaching or exceeding the state-of-the-art 2015 upper bound.

Guo, Yu;Zhang, Lingling;You, Hongjun;Fang, Jixiang research published 《 A solution-based SERS sensing protocol via the ultra-rapid and highly efficient molecule enrichment strategy》, the research content is summarized as follows. The solution-based SERS detection has been considered as one of the most mature com. SERS detection protocols owing to its features of high sensitivity and timeliness. However, poor mol. generality is a challenge for weakly-adsorbed species, such as anionic mols. and complicated organic compositions, on the surfaces of the plasmonic nanostructures. Many mols. in solution especially the weakly-adsorbed organic pollutants cannot be effectively adsorbed onto the surface of metal nanoparticles quickly due to the low affinities towards the metal, hence showing the weak Raman activity. Herein, we report a solution-based SERS sensing protocol via the highly efficient mol. enrichment strategy to achieve highly sensitive detection in solution With the help of pH adjustment in solution, the porous β-cyclodextrin polymer/magnetic nanoparticles (PCDPMNs) can availably capture various types of mols., including cationic dyes (e.g., methylene blue and crystal violet), anionic pigment (e.g., sunset yellow), and neutral organic pollutants (e.g., carbendazim and bisphenol A). Based on the mol. enrichment strategy, the enrichment factors of various mols. are up to 10²-10³, thus their Raman signals are enhanced by 2-3 orders of magnitude. The mol. enrichment strategy provides a new way for the practical SERS detection to improve the ultra-trace detection in solution

Dithiine linkage formation via a dynamic and self-correcting nucleophilic aromatic substitution reaction enables the de novo synthesis of a porous thianthrene-based two-dimensional covalent organic framework (COF). For the first time, this organo-sulfur moiety is integrated as a structural building block into a crystalline layered COF. The structure of the new material deviates from the typical planar interlayer π-stacking of the COF to form undulated layers caused by bending along the C-S-C bridge, without loss of aromaticity and crystallinity of the overall COF structure. Comprehensive exptl. and theor. investigations of the COF and a model compound, featuring the thianthrene moiety, suggest partial delocalization of sulfur lone pair electrons over the aromatic backbone of the COF decreasing the band gap and promoting redox activity. Postsynthetic sulfurization allows for direct covalent attachment of polysulfides to the carbon backbone of the framework to afford a mol.-designed cathode material for lithium-sulfur (Li-S) batteries with a minimized polysulfide shuttle. The fabricated coin cell delivers nearly 77% of the initial capacity even after 500 charge-discharge cycles at 500 mA/g c.d. This novel sulfur linkage in COF chem. is an ideal structural motif for designing model materials for studying advanced electrode materials for Li-S batteries on a mol. level.

Han, Jiuli;Jiang, Haiyan;Zeng, Shaojuan;Bai, Yinge;Zhang, Xiangping;Bai, Lu research published 《 CO₂ separation performance for PIM based mixed matrix membranes embedded by superbase ionic liquids》, the research content is summarized as follows. Mixed matrix membranes (MMMs) have drawn much interest in CO₂ separation due to their excellent separation performance, mech. property, and desirable processability. However, obtaining highly compatible MMMs is a great challenge and is vital to avoid the loss of the separation selectivity of the MMMs. In this work, superbase ionic liquid (1,8-diazabicyclo[5,4,0]undec-7-ene imidazole ([HDBU][Im])) was used as a wetting agent to increase the interfacial compatibility between ZIF-67 and PIM-1, hence improving the membrane gas separation [HDBU][Im] embeding into the MMMs could efficiently enhance the compatibility and diminish the interfacial voids. Furthermore, incorporating 5 wt% [HDBU][Im]@ZIF-67 nanocomposite into the PIM-1 matrix improves the gas permeability and CO₂ selectivity. The separation performances under the different temperatures were also conducted and showed that reducing temperature slightly decreases the gas permeability but significantly increases the CO₂/CH₄ selectivity via enhancing the CO₂ solubility The permeation active energies, diffusivities and solubilities were obtained to explain the gas permeate mechanism.

Han, Weiyao;Zhang, Caili;Zhao, Min;Yang, Fan;Yang, Yang;Weng, Yunxuan research published 《 Post-modification of PIM-1 and simultaneously in situ synthesis of porous polymer networks into PIM-1 matrix to enhance CO₂ separation performance》, the research content is summarized as follows. Post-modification of the chem. structures can be used to tailor the properties of polymers of intrinsic microporosity (PIM-1), which shows promise for application of PIM-1 gas separation membrane. Methane sulfonic acid (MSA) is capable of hydrolyzing and crosslinking nitrile groups of PIM-1 to form carboxylic acid-contained and triazine groups crosslinked PIM-1 (cPIM-1), and simultaneously catalyze in situ synthesis of porous polymer networks (PPNs) in PIM-1 matrix. These reactions were carried out at the same time by a one-step method. Characterization of hydrolysis and crosslinking process of nitrile groups in PIM-1 was performed by ATR, XPS, solubility, and ¹H NMR anal. MSA catalyzed synthetic approach of PPNs includes the trimerization of three acetyl groups and involves a coupled process of polymerization and membrane architecture formation. Finally, the process of crosslinking and hydrolysis can provide enhanced gas pair selectivity of PIM-1 membrane (cPIM-1) while the gas permeability of the membranes (cPIM-1/PPNs) can be increased by the incorporation of PPNs microstructure networks. As a result, the optimal cPIM-1/PPNs showed Roberson’s 2008 upper bound separation performance for CO₂/CH₄ and CO₂/N₂. The cPIM-1/PPN2-3% membrane demonstrated the best CO₂ comprehensive separation performance with the permeability of almost 11511 Barrer, with ideal selectivity of 24.3 and 22.2 for CO₂/N₂ and CO₂/CH₄ resp. Furthermore, the cPIM-1/PPNs membranes show excellent anti-aging properties. This indicates that MSA-catalyzed hydrolysis, crosslinking and in situ synthesis PPNs can effectively adjust the topol. structure of PIM-1 membrane for CO₂ separation
