    Electrochemical polymer synthesis usually forms dense films bound to the electrode. We report a single-step synthesis of large-area, ultrathin (~70-nanometer) polymeric membranes with a luffa-like, reticular cross-linked network with low density (0.5 grams per cubic centimeter). This particular membrane forms within an electric double layer in water constructed by voltage application without supporting electrolytes—in which deprotonated resorcinol and an aldehyde react three-dimensionally with a self-termination mechanism—and is spontaneously released when the voltage bias is removed. Initially rigid with a Young’s modulus of 8.9 gigapascals, this membrane reversibly regains flexibility (0.5 gigapascals) upon wetting and can be used as a large-area membrane for separations. Its shape-persistent carbonization made it possible to yield ultrathin (~22-nanometer) nanoporous carbon membranes.

    ABSTRACT In most cases, atopic dermatitis (AD) is induced by allergic inflammation, with antigen penetration into the epithelial tissues of the skin being the first step in AD development. Accordingly, inhibiting the skin penetration of antigens is effective in preventing AD. We evaluated the ability of the following four types of particles to adsorb ovalbumin (OVA): titanium dioxide (TiO2), silicon dioxide (SiO2), carbon, and SiO2 coated with one‐layer graphene (1LGCS). We found that metal oxide particles (TiO2 and SiO2) could adsorb OVA at pH 5.0, but their abilities decreased at pH 7.0 and 9.0. In contrast, the carbon‐based particles (carbon and 1LGCS) adsorbed OVA regardless of pH changes. Epicutaneous treatment with OVA resulted in an increase in the proportion of OVA‐positive Langerhans cells and dermal dendritic cells in the lymph nodes, along with elevated interleukin‐4 mRNA expression, indicating that OVA penetrated the epidermis and underlying tissues. When OVA was applied together with the particles, these responses were significantly reduced by the carbon‐based particles but were only partially or not inhibited by metal oxide particles. These findings indicated that antigen penetration was potently inhibited by the carbon‐based particles. Additionally, when mice were epicutaneously sensitised and challenged with OVA in the presence of carbon, the increase in OVA‐specific IgG1 and IgE levels was significantly inhibited. The efficiency of carbon‐based particles may be attributed to their stable adsorption of proteins despite pH changes on the skin surface. These findings may lead to the development of new treatments for AD with fewer side effects.

    Supported metal single atom catalysis is a dynamic research area in catalysis science combining the advantages of homogeneous and heterogeneous catalysis. Understanding the interactions between metal single atoms and the support constitutes a challenge facing the development of such catalysts, since these interactions are essential in optimizing the catalytic performance. For conventional carbon supports, two types of surfaces can contribute to single atom stabilization: the basal planes and the prismatic surface; both of which can be decorated by defects and surface oxygen groups. To date, most studies on carbon‐supported single atom catalysts focused on nitrogen‐doped carbons, which, unlike classic carbon materials, have a fairly well‐defined chemical environment. Herein we report the synthesis, characterization and modeling of rhodium single atom catalysts supported on carbon materials presenting distinct concentrations of surface oxygen groups and basal/prismatic surface area. The influence of these parameters on the speciation of the Rh species, their coordination and ultimately on their catalytic performance in hydrogenation and hydroformylation reactions is analyzed. The results obtained show that catalysis itself is an interesting tool for the fine characterization of these materials, for which the detection of small quantities of metal clusters remains a challenge, even when combining several cutting‐edge analytical methods.

    Abstract Porous carbons are important electrode materials for supercapacitors. One of the challenges associated with supercapacitors is improving their energy density without relying on pseudocapacitance, which is based on fast redox reactions that often shorten device lifetimes. A possible solution involves achieving high total capacitance (Ctot), which comprises Helmholtz capacitance (CH) and possibly quantum capacitance (CQ), in high‐surface carbon materials comprising minimally stacked graphene walls. In this work, a templating method is used to synthesize 3D mesoporous graphenes with largely identical pore structures (≈2100 m2 g−1 with an average pore size of ≈7 nm) but different concentrations of oxygen‐containing functional groups (0.3–6.7 wt.%) and nitrogen dopants (0.1–4.5 wt.%). Thus, the impact of the heteroatom functionalities on Ctot is systematically investigated in an organic electrolyte excluding the effect of pore structures. It is found that heteroatom functionalities determine Ctot, resulting in the cyclic voltammetry curves being rectangular or butterfly‐shaped. The nitrogen functionalities are found to significantly enhance Ctot owing to increased CQ.

    Abstract Although lithium–oxygen batteries have attracted attention due to their extremely high energy densities, rational design, and critical evaluation of high‐energy‐density cathode for practical Li–O2 batteries is still urgently needed. Herein, the multiscale, angstrom‐to‐millimeter, precisely controllable synthesis of binder‐free cathodes with minimally stacked graphene free from edge sites is demonstrated. The proposed Li–O2 battery, based on a hierarchically porous cathode with a practical mass loading of >4.0 mg cm−2, simultaneously exhibits an unprecedented specific areal (>30.0 mAh cm−2), mass (>6300 mAh g−1), and volumetric (>480 mAh cm−3) capacities. The battery displays the optimal energy density of 793 Wh kg−1 critically normalized to the total mass of all active materials including electrolytes and even discharge products Li2O2. Comprehensive in situ characterizations demonstrate a unique discharge mechanism in hierarchical pores which contributes to competitive battery performance. Superior rate performance in a current density range of 0.1 to 0.8 mA cm−2 and long‐cycle stability (>260 cycles) at a current density of 0.4 mA cm−2, outperforming state‐of‐the‐art carbon cathodes. This study yields insight into next‐generation carbon cathodes, not only for use in practical Li–O2 batteries, but also in other metal–gas batteries with high energy densities.

    Abstract Hierarchically porous carbon microlattices (HPCMLs) fabricated by using a composite photoresin and stereolithography (SLA) 3D printing is reported. Containing magnesium oxide nanoparticles (MgO NPs) as porogens and multilayer graphene nanosheets as UV‐scattering inhibitors, the composite photoresin is formed to simple cubic microlattices with digitally designed porosity of 50%. After carbonization in vacuum at 1000 °C and chemical removal of MgO NPs, it is realized that carbon microlattices possessing hierarchical porosity are composed of the lattice architecture (≈100 µm), macropores (≈5 µm), mesopores (≈50 nm), and micropores (≈1 nm). The linear shrinkage after pyrolysis is as small as 33%. Compressive strength of 7.45 to 10.45 MPa and Young's modulus of 375 to 736 MPa are achieved, proving HPCMLs a robust mechanical component among reported carbon materials with a random pore structure. Having a few millimeters in thickness, the HPCMLs can serve as thick supercapacitor electrodes that demonstrate gravimetric capacitances 105 and 13.8 F g−1 in aqueous and organic electrolyte, reaching footprint areal capacitances beyond 10 and 1 F cm−2, respectively. The results present that the composite photoresin for SLA can yield carbon microarchitectures that integrate structural and functional properties for structural energy storages .

    The rational design of a stable and catalytic carbon cathode is crucial for the development of rechargeable lithium-oxygen (Li-O2 ) batteries. An edge-site-free and topological-defect-rich graphene-based material is proposed as a pure carbon cathode that drastically improves Li-O2 battery performance, even in the absence of extra catalysts and mediators. The proposed graphene-based material is synthesized using the advanced template technique coupled with high-temperature annealing at 1800 °C. The material possesses an edge-site-free framework and mesoporosity, which is crucial to achieve excellent electrochemical stability and an ultra-large capacity (>6700 mAh g-1 ). Moreover, both experimental and theoretical structural characterization demonstrates the presence of a significant number of topological defects, which are non-hexagonal carbon rings in the graphene framework. In situ isotopic electrochemical mass spectrometry and theoretical calculations reveal the unique catalysis of topological defects in the formation of amorphous Li2 O2 , which may be decomposed at low potential (∼ 3.6 V versus Li/Li+ ) and leads to improved cycle performance. Furthermore, a flexible electrode sheet that excludes organic binders exhibits an extremely long lifetime of up to 307 cycles (>1535 h), in the absence of solid or soluble catalysts. These findings may be used to design robust carbon cathodes for LiO2 batteries.

    Single-site catalysts have isolated metal atoms fixed on a support. Recently, this type of catalyst is received attention because of their well-defined active sites and high activities. In this study, we successfully synthesized single-site cobalt catalysts using Co(salen) complex as a precursor and activated carbon as a support by controlling calcination temperature. In the oxidation of ethylbenzene, the catalyst showed high activity with an improved selectivity for acetophenone compared to unsupported Co(salen) complex, resulting from high-dispersed Co species.&nbsp; <br>

    カーボン新素材「グラフェンメソスポンジ(GMS)」は、単層グラフェンを主成分とするエッジフリーのメソ多孔性カーボンであり、高比表面積、高細孔容積、高導電率、高耐食性を併せ持つ上に、従来の多孔性カーボンには無かった機械的柔軟性を兼ね備えたユニークな材料である。さらに構造制御の自由度が高く、細孔径、エッジの量、官能基、ドーピング、二次粒径、形状(粉末orバルク体)、グラフェン積層数などを用途に応じて調節できる。そこで本研究ではGMSの社会実装に向け、エネルギー、センサー、食品といった複数の領域で具体的な製品を想定した材料の最適化と性能実証を行う。

In this study, we succeeded in establishing an ultra-high temperature and high-sensitivity TPD measurement system and achieved simultaneous qualitative and quantitative analysis of nitrogen-containing carbon materials. This method is applicable even to trace amounts of nitrogen content, and is a novel analytical method that complements conventional methods such as XPS and CHN elemental analysis. The target materials are not limited to nitrogen-containing carbons, and further development is expected as a new analytical method for trace amounts of heteroatoms in various materials.
