Foamed silicone rubber was prepared by mixing 45% vinyl silicone oil (Base), Karstedt platinum catalyst (Cata), and hydrogenated silicone oil (SiH) and the resulting material was subjected to secondary vulcanization, which led to its performance requirements. Vinyl silicone oil and hydrogenated silicone oil underwent an addition reaction under the action of a platinum catalyst to form an elastomer with a cross-linked network structure. The results showed that by increasing the content of hydrogenated silicone oil in the formulation, the elongation at break of the foamed silicone gel material decreased but the tensile strength increased. When the content of hydrogenated silicone oil in the formulation decreased, the elongation at break of the foamed silicone material increased. When the content of Karstedt catalyst in the formulation increased, the formation time of the reaction gel was greatly shortened, and the cell structure tended to be dense but delicate. When the proportion of vinyl silicone oil in the formulation increased, the elongation at break of the foamed, molded silicone rubber increased. However, the elastic modulus decreased, and the thermal stability improved. Finally, a more suitable formulation of VBase:VCata:VSiH = 32:1:2 was obtained, which showed a tear resistance of 5.52 KN/m, ductility of 133%, and limiting oxygen index of 26 with a stability temperature of 346.8 °C when the thermal mass loss reached 95%.

The development of advanced carbon materials is indispensable for high-performance supercapacitors. Herein, we report the direct pyrolysis of waste coal-tar pitch (CTP) with ZnO nanoparticles (Zn NPs) to produce hierarchical porous carbon materials (HPCs). The CTP served as a carbon source, and the embedded ZnO NPs as a simultaneous templating and activating agent for HPCs. At an optimum temperature of 800 °C, the produced HPCs (HPC-800) realized an optimal specific surface area (1267 m2 g-1) and pore volume of 1.71 cm3 g-1, enabling the devised capacitor to exhibit a specific capacitance of 172 F g-1 at a current density of 0.1 A g-1 in 6 M KOH electrolyte and a capacitance retention of 81% (0.1–30 A g-1). The as-symmetrical device could deliver an energy density of 8.3 Wh∙kg-1 at a high-power density of 50.0 W∙kg-1 and retained energy density of 4.9 Wh∙kg-1 at a power density of 11.9 kW∙kg-1.

To study the behavior of Mn2+ ions and water molecules in Mn2+-exchanged zeolite Y (Si/Al = 1.67) at different temperatures during dehydration, single crystals of Mn2+-exchanged zeolite Y were prepared by batch method at room temperature. Five single crystals of Mn2+-exchanged zeolite Y were dehydrated at 297 K (crystal 1), 523 K (crystal 2), 573 K (crystal 3), 623 K (crystal 4), and 673 K (crystal 5), respectively, under dynamic vacuum for 48 h. Their crystal structures were determined by single-crystal synchrotron X-ray diffraction techniques in the cubic space group Fd(overline{3 })m at 100(1) K. They were refined to the final error indices R1/wR2 = 0.0594/0.1615, 0.0450/0.1229, 0.0445/0.1108, 0.0447/0.1145, and 0.0418/0.1084 (for Fo > 4σ(Fo)) for crystals 1, 2, 3, 4, and 5, respectively. In all five crystals, about 36 Mn2+ ions occupy five crystallographic sites. Mn2+ ions are energetically preferentially located at site I in all structures. The Mn2+ ions migrated from one site (sites I’ or II’) to another available site (sites I or II) to better satisfy their coordination requirements upon dehydration. Finally, in the completely dehydrated crystal 5, 36 Mn2+ ions occupy the sites I, I’, II’, IIa, and IIb with the fractional occupancies 15, 2, 2, 12, and 5, respectively. All water molecules associated with Mn2+ ions in the incompletely dehydrated crystals 1 ~ 4 were located in the sodalite cavities. In the structure of crystal 1, about 10.5 water molecules were found per unit cell, each coordinating to Mn2+ ions at Mn(1’b). These water molecules formed clusters as [Mn4(H2O)4]8+. Only 5, 3, and 2 water molecules were found in the structures of crystals 2 ~ 4, respectively, with increasing temperature. Each of these water molecules was bonded to one Mn2+ ion at Mn(2’), forming [MnH2O]2+. The unit cell constant of the zeolite framework decreased, as the number of water molecules decreased with the increasing dehydration temperature.

The effect of post-treatment of TS-1 zeolite by tetrapropyl ammonium hydroxide aqueous solution under hydrothermal condition was studied in this work. The characterizations of structure, morphology and composition demonstrated that an open and hierarchical porous structure was generated in TS-1 zeolite after the post-treatment. With increasing the alkalinity of TPAOH solution, the hierarchical porosity and hydrophobicity increased and the framework Ti content decreased in the post-treated TS-1 zeolite. Both the pristine and post-treated TS-1 zeolites were employed as the catalysts for the reaction of phenol hydroxylation. It was found that the post-treated TS-1 zeolite possessed a higher catalytic performance than the pristine TS-1 zeolite. The larger the alkalinity of the post-treatment solution was, the higher the catalytic performance of the post-treated TS-1 zeolite was; however, a too high alkalinity of the post-treatment solution also led to the decline in the catalytic performance. This could be a result of the combined influences of the hierarchical porosity, hydrophobicity and framework Ti content on the catalytic performance. The higher levels of hierarchical porosity and hydrophobicity promoted but the lower level of framework Ti content inhibited the catalytic performance of TS-1 zeolite. Accordingly, the controlling to the alkalinity of TPAOH solution for the post-treatment was very important in respect of the catalytic performance of TS-1 zeolite.
这项工作研究了在水热条件下用四丙基氢氧化铵水溶液对 TS-1 沸石进行后处理的效果。对结构、形态和组成的表征表明,经过后处理后,TS-1 沸石中产生了一种开放的、分层的多孔结构。随着 TPAOH 溶液碱度的增加,经后处理的 TS-1 沸石的分层孔隙率和疏水性增加,框架 Ti 含量降低。原始和后处理的 TS-1 沸石都被用作苯酚羟基化反应的催化剂。结果发现,经过后处理的 TS-1 沸石比原始 TS-1 沸石具有更高的催化性能。后处理溶液的碱度越大,后处理 TS-1 沸石的催化性能越高;但是,后处理溶液的碱度过高也会导致催化性能下降。这可能是分层孔隙率、疏水性和框架 Ti 含量对催化性能的综合影响。较高的分层孔隙率和疏水性会促进 TS-1 沸石的催化性能,但较低的框架 Ti 含量则会抑制 TS-1 沸石的催化性能。因此,控制后处理 TPAOH 溶液的碱度对 TS-1 沸石的催化性能非常重要。

Spherical AlPO4 supported WO3 catalysts were synthesized and characterized by XRD, N2 sorption isotherm, SEM, TEM and NH3-TPD, and used as a catalyst for the production of Euro 95 standard gasoline fuel additives from biomass-derived furfural via reductive etherification. Compared with the AlPO4 catalyst, the surface acidity increased after the impregnation of tungsten oxide. The activity and stability of the catalysts also improved with the impregnation of tungsten oxide on AlPO4. However, the existing catalytic system cannot provide high conversion to furfural and selectivity to ether due to the formation of side reactions. To optimize the reaction conditions, the effect of temperature, catalyst amount, furfural/isopropanol molar ratio, and choice of hydrogen donor were studied. Under these optimized conditions, a high conversion of furfural (92%) and a yield of isopropyl furfuryl ether (IPFE) (83%) were obtained with the byproducts of furfuryl alcohol and acetal. The WO3/AlPO4 catalyst also achieved a high yield of ether with various aldehydes and alcohols via reductive etherification.

The discharge of dye industry wastewater without any proper treatments has raised tremendous concerns due to its hazardous nature and potential risks. Photocatalytic degradation is a promising technology for environmentally friendly and sustainable treatment of dye pollutants. Nanomaterial-based photocatalysts have been successfully applied to treat industrial dye wastewater. Among them, titanium dioxide (TiO2) with diverse nanostructure and numerous advantages has garnered significant attentions. However, the morphological difference of TiO2 is of paramount importance for enhancing its degradation performance. This review provides an overview of recent advances in various forms of multidimensional TiO2, including 0D nanoparticles, 1D nanowires, nanotubes, nanofibers, and nanorods, 2D nanosheets and nanoplates, as well as assembled 3D micro-nano structures, for photocatalytic dye wastewater treatment. The article could briefly elaborate the conventional synthesis routes, advantages, challenges, and application areas of TiO2 in different dimensions, and compares their photocatalytic degradation performance and mechanisms. Simultaneously, these approaches of modified performances by doping metal ions and non-metal ions have emphatically involved over here. Noteworthily, the insights into the future trends, challenges, and prospects of multidimensional TiO2 materials have been also proposed.
