Wang, Zijie;Chen, Hongni;Gao, Xing;Hu, Bo;Meng, Qingli;Zhao, Chuanliang;Yang, Liwei;Zheng, Huaili research published 《 A novel self-floating cyclodextrin-modified polymer for cationic dye removal: Preparation, adsorption behavior and mechanism》, the research content is summarized as follows. The separation and recycling processes of current cyclodextrin (CD)-based adsorbents are complicated. Thus, a novel composite based on a large surface area, porous, and self-floating tetrafluoroterephthalonitrile (TFN)-crosslinked CD polymer (FTFCD), was fabricated, characterized and applied to treat cationic dye pollutants. The characterization showed a porosity, good thermal stability, a stable crystal structure, and abundant functional groups on the prepared FTFCD, which had demonstrated great improvement on its adsorption capacity towards attention grabbing pollutants. The removal efficiency of the adsorbents for malachite green (MG) remained above 95% at pH 1 ∼ 10. In addition, the adsorbents were found to rapidly reach equilibrium governed by the pseudo-second-order kinetic model, and the maximum adsorption capacity of FTFCD was 1390.263 mg/g, as corroborated by the Langmuir isotherm model. While the phenolate groups of FTFCD found to electrostatically interacts with the MG strong cationic quaternary amine group, hydrogen-bonding was responsible for the hydroxyl group of FTFCD and the quaternary amine group binding. Meanwhile, the triangular cone configuration of MG makes it easy to be entrapped and absorbed in the hydrophobic cavity. Besides, after regeneration of exhausted FTFCD for five successive cycles, the MG removal efficiency still reached more than 80%. Thus, FTFCD could be applied as a potential alternative adsorbent for cationic dye removal owing to its excellent adsorption performance, convenient recycling, wide pH application, and environmental friendliness.

In this study, a phthalocyanine indium (InPcOH) and three porphyrin derivatives (Por2a, Por2b, Por2c) were successfully synthesized. Three kinds of novel four-arm star-shaped poly(propylene oxide) (PPO) with core of InPcOH and chain-end of porphyrin derivatives, named InPc-(PPO_x-Por2n)₄ (n = a-c), were achieved through the InPcOH as initiator by ring-opening polymerization From fluorescence spectra, InPc-(PPO_x-Por2n)₄ polymers revealed weaker emission intensity at 704 nm in comparison with InPc-(PPO29)4, proving energy transfer (ET) pathway from Por2a-2c to InPc, which could be established by theor. study.

Wang, Liang;Guo, Xiang;Zhang, Feng;Li, Nanwen research published 《 Blending and in situ thermally crosslinking of dual rigid polymers for anti-plasticized gas separation membranes》, the research content is summarized as follows. The polybenzimidazoles (PBI) has been employed as blends and macromol. crosslinkers into bromomethylated polymers of intrinsic microporosity (PIM-Br) to prepare anti-plasticized gas separation membrane. Interestingly, the PBI showed excellent miscibility with PIM-Br probably due to the interaction between the benzimidazole and -CN groups, and thus a series of flexible, tough and transparent membranes were obtained by simply blending. After thermal treatment of the blending membrane, the crosslinked PIM-Br/PBI membranes with ionic and covalent crosslinking were achieved as confirmed by XPS results. Although the blending PIM-Br/PBI membranes showed the decreased gas permeabilities due to the lower gas permeability of PBI moieties, the increased gas permeabilities of PIM-Br/PBI membrane has been observed after crosslinking without significant sacrificing of selectivity. Moreover, higher crosslinking temperature induced the higher gas permeability. The PIM-Br/PBI membrane having PBI content of 5 wt% treated at 300°C has a CO₂ permeability of 3313.7 Barrer which is much higher than that of the PIM-Br/PBI blending membrane (1645.3 Barrer) probably due to the formation of more open matrix in membrane after crosslinking. However, comparable CO₂/CH₄ selectivity of ∼13 were observed for all of the crosslinked membranes. Importantly, both of the blending and thermal crosslinking between PIM-Br and PBI resulted in the excellent CO₂ anti-plasticization ability of the membrane. Particularly, a single gas plasticization pressure as high as more than 600 psi and mixed-gas plasticization resistance for crosslinked PIM-Br/PBI have been observed This value is much higher than that of the pristine PIM-Br membrane (100 psi).

The basic characterizations revealed that CuTAPc-MCOF demonstrated extended π-system and possessed the phenanthroline group, which can be coordinated with Ag. Consequently, it endowed the CuTAPc-MCOF@AgNPs nanohybrid with good biol. compatibility, boosted electron transfer, and produced abundant catalytic active sites. As such, the CuTAPc-MCOF@AgNPs nanohybrid illustrated superior biocompatibility and excellent electrocatalytic activity, thereby showing remarkable electrocatalytic performance for electro-oxidizing nitric oxide (NO) released from living cancer cells. The sensing properties of the CuTAPc-MCOF@AgNPs-based sensor were measured by cyclic voltammetry and amperometry techniques. The CuTAPc-MCOF@AgNPs-based electrochem. sensor showed a high sensitivity of 29.1 ΜA ΜM^-1 cm^-2 and a low detection limit of 12.6 nM within the concentration range of 0.18 ΜM to 17.1 ΜM toward NO, together with excellent selectivity, high reproducibility and repeatability, and good stability.

Wang, Shuai;Deng, Li-Hong;Du, Yi-Fei;Song, Xian-Liang research published 《 Graphene carbon black as catalyst support: The influences of iron phthalocyanine loading and carbon black additive amount on the power generation performance of direct glucose fuel cell》, the research content is summarized as follows. Fast accessibility of oxygen reduction reaction (ORR) species to a catalyst surface with the efficient utilization of every catalytic site plays a critical role in catalysis. Therefore, engineering of the structure and morphol. of catalyst supports to both anchor and expose catalytic sites at three-phase-boundaries, accelerating the mass transport of reaction-species through the active sites, can be regarded as one of the most prospective methods to promote the efficient utilization of every catalytic site, giving prominent cell performance. Herein, two series of oxygen reduction reaction catalysts are prepared: reduced graphene oxides (rGO) with different loading amounts of iron phthalocyanine TFePc/rGO-X (X = 1,2,3,4 and 5); and TFePc/rGO-3 that is intercalated by different amounts of carbon black TFePc/rGO/CB-Y (Y = 1,2,3,4 and 5). The catalytic activities and stabilities of these catalysts were evaluated by cyclic voltammetry and linear sweep voltammetry. As expected, the 3D rGO/CB/rGO network is demonstrated as a singular catalyst-loading platform, with interlayer spacing that could be elaborately tuned via a simple carbon black intercalation. This enables ORR-species to be efficiently transported to each catalytic site. Besides, the optimal catalyst of TFePc/rGO/CB-3 exhibits more pos. ORR peak potential than Pt/C catalyst. More significantly, in a practical cell, the cell performances were highly consistent with ORR active and the first-best cell performance of 0.86 mWcm-2 in power d. was achieved for TFePc/rGO/CB-3. This is mainly attributed to the synergistic effect of rGO and carbon black, as well as the π-π interaction between rGO and TFePc.
