Propyl–SO3H functionalized SBA-15: Microwave-mediated green synthesis of biologically active multi-substituted imidazole scaffolds

Gabla, Jenifer J.; Lathiya, Dharmesh R.; Revawala, Akash A.; Maheria, Kalpana C.

Propylsulfonic acid functionalized Santa Barbara Amorphous-15 (SBA-15–Pr–SO3H) catalyst has been synthesized using a surface modification of mesoporous SBA-15 via the one-pot co-condensation method. The synthesized SBA-15–Pr–SO3H has been characterized by peculiar characterization techniques such as small- and wide-angle XRD, SEM–EDX, TEM, TG–DTA, acidity, FT-IR, Py-FT-IR and BET surface area…

Kinetics-controlled synthesis of hierarchically porous materials with tunable properties from diverse building blocks

Xie, Lei; Wang, Zhe; Liu, Jinrong; Gong, Yutong; Mao, Shanjun; Lü, Guofeng; Ma, Xiao; Yu, Lili; Wang, Yong

The easy hydrothermal method is a potential candidate for the preparation of carbohydrate-derived hierarchically porous polymers (HPPs) and carbons (HPCs). However, owing to the uncontrolled reaction rate and the weak affinity between precursors and soft templates, the synthesis of HPPs and HPCs with tunable properties through this method remains a…

Shape and phase controlled synthesis of mesostructured carbon single crystals through mesoscale self-assembly of reactive monomicelles and their unprecedented exfoliation into single-layered carbon nanoribbons

Wang, Tianping; Sun, Yanbin; Wu, Jiali; Liu, Xiangyang; Pan, Ruping; Liu, Xikui

The formation of mesostructured polymer and carbon single-crystals is very difficult due to increased complexity of the energy hypersurface and the role of slowed-down kinetics. Here we reported the synthesis of ordered mesostructured phloroglucinol-formaldehyde single crystals through mesoscale self-assembly of reactive monomicelles under acidic conditions which were traditionally thought very…

TiO2-carbon nanoporous composites prepared via ZnO nanoparticle-templated carbonization of glucose adsorb and photodegrade organic pollutants in water

Barrera, Luis A.; Escobosa, Alma C.; Nevarez, Aileen; Dominguez, Noemi; Bañuelos, Jose L.; Westerhoff, Paul; Noveron, Juan C.

We report the ZnO nanoparticle-templated formation of nanoporous carbon (NTC) embedded with TiO2 nanoparticles for the adsorption and photodegradation of organic pollutants in water. Small-angle X-ray scattering (SAXS) studies indicate that NTC and NTC-TiO2 exhibit two types of porosities with average pore diameters of 2.8 and 11.5?nm, while Brunauer-Emmet-Teller (BET)…

Niobium dioxide (NbO2) features a high theoretical capacity and an outstanding electron conductivity, which makes it a promising alternative to the commercial graphite negative electrode. However, studies on NbO2 based lithium-ion battery negative electrodes have been rarely reported. In the present work, NbO2 nanoparticles homogeneously embedded in a carbon matrix…

Unveiling the role of hydrothermal carbon dots as anodes in sodium-ion batteries with ultrahigh initial coulombic efficiency

Xie, Fei; Xu, Zhen; Jensen, Anders C. S.; Ding, Feixiang; Au, Heather; Feng, Jingyu; Luo, Hui; Qiao, Mo; Guo, Zhenyu; Lu, Yaxiang; Drew, Alan J.; Hu, Yong-Sheng; Titirici, Maria-Magdalena

Hard carbon materials are regarded as the most promising anode materials for sodium-ion batteries (SIBs) due to their best cost-effectiveness. However, their relatively low specific capacity and initial Coulombic efficiency (ICE) compared with the graphite anode in lithium-ion batteries still limit the energy density for further development. Thus, it is…

Regulating Pore Structure of Hierarchical Porous Waste Cork-Derived Hard Carbon Anode for Enhanced Na Storage Performance

Li, Yuqi; Lu, Yaxiang; Meng, Qingshi; Jensen, Anders C. S.; Zhang, Qiangqiang; Zhang, Qinghua; Tong, Yuxin; Qi, Yuruo; Gu, Lin; Titirici, Maria-Magdalena; Hu, Yong-Sheng

Porous structure design is generally considered to be a reliable strategy to boost ion transport and provide active sites for disordered carbon anodes of Na-ion batteries (NIBs). Herein, a type of waste cork-derived hard carbon material (CC) is reported for efficient Na storage via tuning the pore species. Benefiting from…

Highly Stretchable Photonic Crystal Hydrogels for a Sensitive Mechanochromic Sensor and Direct Ink Writing

Chen, Jiayao; Xu, Lirong; Yang, Meijia; Chen, Xiaochuan; Chen, Xudong; Hong, Wei

Photonic crystals, which are materials with periodic dielectric constants on the submicroscale, have been the focus of research for an extended period. Photonic soft materials have been extensively developed for use as colorimetric indicators and mechanochromic sensors, but their limited mechanical properties and molding characteristics only suitable for films restrict…

Crystal Chemistry and SAXS Studies of an Octahedral Polyoxoarsenotungstate Nanocluster Encapsulating Four Unprecedented Thorium Arsenate Fragments (Th3As2On – n = 25 or 26)

Dufaye, Maxime; Duval, Sylvain; Stoclet, Grégory; Loiseau, Thierry

The reaction of 8– with the 5f tetravalent thorium cation in presence of an acetate buffer and KCl at pH = 4.7 gives rise to the formation of an octahedral polyoxoarsenotungstate nanocluster 38–. This molecule is constructed around four unprecedented Th3As2On (n = 25 or 26) fragments stabilized by the…

In-Depth Study of Coating Multimodal Porosity Using Ellipsometry Porosimetry in Desorption Scanning Mode

Loizillon, Jérôme; Baumgartner, Bettina; Sinturel, Christophe; Abbarchi, Marco; Lendl, Bernhard; Grosso, David

Ellipsometry porosimetry provides full adsorption/desorption isotherms and is among the most accurate techniques to probe porosity in thin films. Here we address a novel technique based on desorption scanning for a precise assessment of the porosity features revealing the size distribution of interconnections between the various populations of pores in…
