    Abstract Hollandite‐type α‐MnO2 exhibits exceptional promise in current industrial applications and in advancing next‐generation green energy technologies, such as multivalent (Mg2+, Ca2+, and Zn2+) ion battery cathodes and aerobic oxidation catalysts. Considering the slow diffusion of multivalent cations within α‐MnO2 tunnels and the catalytic activity at edge surfaces, ultrasmall α‐MnO2 particles with a lower aspect ratio are expected to unlock the full potential. In this study, ultrasmall α‐MnO2 (&lt;10 nm) with a low aspect ratio (c/a ≈ 2) is synthesized using a newly developed alcohol solution process. This material demonstrates exceptional performance across various multivalent battery systems, primarily due to the significantly reduced cation diffusion distance. Notably, an ultrasmall α‐MnO2‐graphene composite achieves high capacity with low overpotential when paired with an F‐free electrolyte in Ca battery. Regarding aerobic oxidation catalysis, the nanosizing of α‐MnO2 has a profound impact on aerobic oxidation catalysis. The increased efficiency of oxidative conversion reactions, such as the oxidation of 1‐phenylethanol, is attributed to the greatly expanded active surface area of the catalyst. The versatile functionality of ultrasmall α‐MnO2 underscores its potential to revolutionize energy storage and catalysis, offering broad applicability in next‐generation green energy technologies.

    Abstract Zinc‐ion batteries (ZIBs) are promising grid‐scale energy storage devices owing to their low cost, high energy/power densities, high safety, benign environmental impact, etc. Among various cathode materials, ZnMn2O4 spinel has attracted attention because of its high theoretical capacity (448 mAh g−1) associated with the two‐electron redox reaction of Mn ions (2+/4+), a higher voltage (≈1.4 V vs Zn/Zn2+) than V2O5‐based cathodes (≈1.0 V), and better cyclability among manganese oxide‐based cathodes. However, so far only the one‐electron reaction of Mn ions is used with ZnMn2O4 spinel (≈224 mAh g−1), impairing its attractive features. In this study, the two‐electron reaction is successfully enabled by synthesizing ultrasmall ZnMn2O4 spinel nanoparticles (≈5 nm) composited with graphene (US‐ZMO/G) via a rapid room‐temperature alcohol reduction process, achieving the reversible capacity of 445 mAh g−1 at the second cycle. As far as it is known, the US‐ZMO/G composite achieves the highest gravimetric energy/power densities among cathodes for ZIBs. The combination of high capacity and high voltage enables an outstanding energy density approaching that of lithium‐ion batteries.

    Graphene nanosheet (GNS) gives rise to an extraordinary modification to the properties of Pt cluster electrocatalysts supported on it. The Pt/GNS electrocatalyst revealed an unusually high activity for methanol oxidation reaction compared to Pt/carbon black catalyst. The Pt/GNS electrocatalyst also revealed quite a different characteristic for CO oxidation among the measured catalyst samples. It is found that Pt particles below 0.5 nm in size are formed on GNS, which would acquire the specific electronic structures of Pt, modifying its catalytic activities.

    More details Close

    A methodology was developed to synthesize crystalline mesoporous metal oxides by help of controlled crystallization process. The proposed methodology has three essential features: (1) Mesoscopically ordered hybrids consisting of multicomponent inorganic precursors and surfactant templates can be obtained by using self-assembly procedure; (2) Subsequent in-situ crystallization of the materials through heat treatment transforms the hybrid into nanocrystal–based oxides; (3) Glass phase is used to control the crystallization. In this way, the nanocomposite consisting of anatase nanocrystals and glass phase can be designed and synthesized. In addition, almost fully crystalline mesoporous oxides can be resulted by decreasing the content of glass phase.

    Strict control of the crystallization of TiO_2 is one of the most important factors in forming mesoporous structured TiO_2 thin films. Effects of the crystallization of TiO_2 on the formation of mesoporous structures have been studied by transmission electron microscopy (TEM) and high-resolution TEM (HRTEM) observation and X-ray diffractometry (XRD) analysis. The obtained well-ordered mesoporous TiO_2 thin films, calcined at 450℃ to remove the template, are composed of a continuous non-crystalline TiO_2 matrix containing TiO_2 nanocrystals, whose mean size is sufficiently small to support the mesostructure. In the mean time, the mesoporous TiO_2 materials that almost lose their ordered structure after calcination consist of large TiO_2 crystallites (over 6 nm), and the overgrowth of TiO_2 crystallites cause a collapse of the mesoporous structure.

    Protonic conductor has been studied for a large number of inorganic and polymer materials because of the technological potential for fuel cells, hydrogen separation and other electrochemical devices (1-3). In this paper, new class of organic/inorganic hybrid membranes have been synthesized through sol-gel processes. The membrane doped with acidic moieties such as tungstic isopolyacids, acidic tungsten oxide clusters and 12-phosphotungstic acid (PWA) shows good protonic conductivities at high temperatures up to 160°C and was found to be a flexible as well as thermally stable due to the temperature tolerant inorganic frameworks in the hybrids. The effect of molecular structure of polymer phase as well as inorganic structures on to the protonic conductivity have been studied.

    In this research project, we have developed a novel co-production processes of mono-layer graphene and hydrogen via hydrothermal cathodic reduction under a subcritical water. In the developed process, the hydrothermal subcritical water solution was used to enhance the electrochemical reaction kinetics due to an increased electrolytic dissociation rate of the water and prevent the formation of undesirable amorphous carbon. The hydrothermal electrochemical reaction enabled low-temperature graphene growth on a Pt cathode surface with simultaneous hydrogen production. The conversion of hydrocarbons/basic chemicals to the high-value-added nanocarbons, including graphene, carbon nanotubes, and fullerenes, with valuable hydrogen has high potential economic/environmental benefits.

    平成28年度に国際共同研究として取り組んだのはモリブデン化合物の1次元クラスターポリマー材料である。硫化モリブデンクラスター(Mo3S11)nはモリブデン原子3個からなるクラスターがペンダント型に連なった1次元無機ポリマーであるがHAADF-STEM観察を用いて構造解析した結果、モリブデン原子3個からなるクラスターが明確に観測され、これらのクラスターが結合したポリマーがコンフォメーション変化を行っているダイナミクスも直接観察できた。この硫化モリブデンの1次元ポリマーの電極特性を調べた結果、非常に高活性な水素還元特性を有していることが判明した。白金に迫る高い電極触媒をレアメタルフリーの化合物から見出したことは低コストの燃料電池やレアメタルフリー化に貢献する革新的なエネルギー機能材料であり、国際共同研究成果は世界トップ誌に掲載された(Nature Materials, 15, 640-646 (2016))。また、東北大の本間研ではこの研究をさらに進め、これらの1次元ポリマー材料の二次電池応用を検討した。現在、移動体電源として多価イオンを可動キャリアとする二次電池、特にマグネシウム電池に注目が集まっているが、硫化モリブデン化合物のマグネシウムイオン電池活物質としての性能を評価したところ、約80mAh/gの高い活物質容量を得ることが出来た。充放電前後の試料に対してXPS分析を行った結果、クラスター表面に存在する硫黄原子の内、末端硫黄原子のぺア(terminal sulfur)と2価のマグネシウムイオンとの可逆的なファラディック反応が生じ、大きな容量を得ることが出来たと考えている。現在、高容量なマグネシウムイオン電池の正極活物質は見つかっていない状況であり、本研究成果はハイインパクトの国際誌に掲載さ入れた。(Nano Letters, 16, 5829-5835 (2016))

    Organic materials has attracted much attention as the electrodes in low-cost, environmentally-friendly and high-energy-density batteries. In this study, we analyzed the crystal structural change in organic electrode, and revealed that the crystal growth of organic compound during charge-discharge cycling can become a dominant mechanism of battery degradation. To avoid the organic crystal growth, the control of interface between electrode and electrolyte was effective. Moreover, by applying the organic active materials to electrochemical flow capacitor, the capacitance enhancement was achieved.

    平成26年度は画期的なナノ結晶電極材料の合成法である超臨界流体合成法を世界最高レベルまで発展させることに挑戦し次世代リチウム二次電池の有力電極材料と目されている高電位オリビン系活物質LiCoPO4や、さらに高容量特性が期待されているLi2CoSiO4およびLi2CoPO4F正極材料などの革新的電極材料のナノ結晶活物質などの新規電極材料の合成プロセス開発と電極特性評価を行うことが出来た。これらは材料化学分野で国際的一流雑誌に発表され国内外で良好な評価を得るとともに電池開発者に有益な学術情報を提供することが出来た(Chemistry - A European Journal, 20, 16210- 16215(2014); Journal of Materials Chemistry A, 2, 17400-17407(2014); RSC Advances, 4, 27452-27470 (2014); Scientific Reports, 4, 3975 (2014))平成26年度の研究開発では超臨界流体プロセスを用いて高電位オリビン化合物Li2CoPO4のナノ結晶活物質の合成に成功し、電極特性を評価した。これらのコバルト系オリビン電極は5V級の極めて高い正極電位を示す一方、充放電サイクルに従い大きく電極容量を減少させることが判明した。その原因をHAADF―STEM解析を用いて解析した結果、これらのLiCoPO4活物質においては充放電サイクルを行うにつれAntisite Defectsが増加することを見出した(Chemistry of Materials, 26, 2770 - 2773(2014))(ACS Applied Materials and Interfaces, 5, 9926–9932(2013))。このようなAntisite Defectsの形成要因を解明し、それらの抑制機構を見出せば安価安定な化合物である新規材料の二次電池応用が進捗するであろう。

    Zigzag-edge nanographene can be a promising magnetic material, which contributes to the magnetic separation and collection of minor metals. In this study, we developed a novel scalable production method of zigzag-edge-introduced nanographene by combination between anisotropic etching and supercritical fluid exfoliation. We conducted anisotropic etching of graphite substrate/powder with catalytic nanoparticles in supercritical water. Anisotropic etching made a lot of trenches consisted of zigzag edges on graphite surface. Because of the exfoliation effect of supercritical fluid, graphene was isolated from the graphite simultaneously with the anisotropic etching. Finally, the multilayer graphene with zigzag edge was exfoliated from the anisotropically etched graphite surface.

    本研究では革新的エネルギーデバイスである金属空気電池の構築のための新規電極・電解質の材料設計を行った。高活性な酸化物電極触媒は金属空気電池の出力特性を向上させることが出来るとともに、水素製造やリチウム空気電池への展開も可能である。特に温暖化対策のキーテクノロジーとして注目されている電気自動車では高エネルギー密度の蓄電池開発が重要であるが、次世代電池としての最有力候補は金属空気電池である。金属空気電池の中でも最高のエネルギー密度を有するのはリチウム空気電池であるが、このタイプの電池では金属リチウムを負極として、空気(酸素ガス)を正極活物質として用いるため、別の見方をすればリチウムを燃料とした燃料電池とも言える。Baek Seung-Wook博士の平成22年度の研究においてはナノ構造電極触媒とリチウムイオン伝導性の固体電解質の設計と材料開発を行い、そのイオン伝導特性の評価を行った。平成22年度、Baek博士の設計した画期的な電解質材料はナノ結晶Li_3PO_4からなる高イオン伝導性でリチウム負極に還元耐性のある新しい固体電解質材料を開発した。ナノ結晶Li_3PO_4とイオン液体とのコンポジット型電解質を作製し、その固体材料としてのリチウムイオン伝導性を評価した結果、10^<-3>S/cmの高いリチウムイオン伝導度を有していることが判明した。これらの新規開発した固体電解質とリチウム金属を接合させヘテロ界面の電気化学的安定性と電荷移動特性を評価した結果、リチウム金属負極への還元耐性を有しながら高い電荷移動特性を有した優れたヘテロ界面が形成されていることが判明した。この新規固体電解質の研究を進捗させ、空気電池と全固体型二次電池への応用を今後検討する。

    平成23年度の研究においては、単原子層シート構造のグラフェンが3次元的に再積層化したキャパシタ電極の新規合成法開発を行った。グラフェンの合成時に酸化マンガンシートを導入して単原子層シートグラフェンとの交互再積層体を中間体として、これにアニリンモノマーを加えた後、マンガン酸化物シートの溶解とその場(in-situ)でのアニリンの酸化重合を同時に行った、これにより、グラフェンシート層間にポリアニリンがスペーサーとして挿入された3次元構造を有したナノグラフェン/ポリアニリン再積層体電極の合成に成功した。この3次元電極は水溶液中(1M-H_2SO_4)で641F/gの非常に巨大なキャパシタ容量を示した、このキャパシタ容量はグラフェン材料において現時点では世界最高値である。この巨大容量の発現は、イオン拡散パスを有した3次元再積層体グラフェンで表面積利用効率が向上したことから電気二重層(EDLC)容量の増大が実現したこと、および、スペーサーとして挿入したポリアニリンの電気化学活性なプロトン容量が加算されたためと考えられる。また、さらに高容量型グラフェン電極開発を目的にナノ結晶活物質が表面修飾された高エネルギー密度型電極の合成法開発と充放電特性評価を行った。研究目標値としたリチウム貯蔵容量800mAh/gの負極容量に迫る性能を達成し、さらにこれらのグラフェン修飾電極の充放電サイクル特性の評価も行った。これらのリチウム電池電極材料の性能は電気自動車用高密度二次電池に要求される電極性能を有しており、グラフェンを効果的に利用した新しい高性能リチウム二次電池電極材料を単原子層シートグラフェンをベースに開発することが出来た。

    本年度は、超臨界水熱合成法を用いた高出力型LiMnPO4正極材料およびLiFePO4などのリチウム二次電池正極材料のナノ結晶活物質の合成法開発を行った。これらのリチウム電池電極材料のナノ結晶活物質の安価かつ量産的プロセスの開発により自動車用の高性能リチウム二次電池の普及を大きく前進させることが出きる。ハイブリッド車用電池材料の開発は温暖化対策において最も重要な先端エネルギー技術であり現在世界的な競争が繰り広げられている。本年度の共同研究のポイントは超臨界流体といった反応媒体として可能性に満ちた系を電極材料の合成に応用する画期的なアイディアを検証することにある。超臨界水熱合成の前駆体の適切な選択や溶液中に様々な界面活性剤を加えることにより前駆体である金属化合物の反応性を精密に制御し、その核生成、核成長、結晶モルフォロジーを制御しながら単分散性で数ナノメートルサイズのナノ結晶電極活物質粒子の量産的合成法を開発した。特にプラグインハイブリッド車用の次世代リチウム二次電池電極材料として期待が掛かるオリビン構造LiFePO4やLiMnPO4の超臨界流体合成を行い、これまで例の無い数十ナノメートルレベルの非常に小さいサイズの電極活物質の合成法開発に成功した。これらの結晶構造をTEMなどの電子顕微鏡観察により解析しバルクと異なるナノサイズ活物質の結晶学的特長を明らかにし。さらにナノサイズ活物質の電気化学特性、リチウム二次電池電極活性、充放電サイクル特性などを測定した。平成22年度に置いては、さらに電極材料の作製を高度化して、電池技術に必須の高機能性カーボン電極材料の超臨界流体による合成も試みた。単原子層シートのグラフェンをグラファイトの超臨界流体処理で合成し、その量産性の評価、さらには単原子層特有の炭素構造評価と電気化学特性の評価を行い、リチウム電池電極への応用を検討した。

    MOCVD法を用いてSiあるいはPt基板上にPbTiO_3、SrTiO_3薄膜を合成した。有機金属の供給原料ガスとしてSr(DPM)_2、Pb(DPM)_2とTi(DPM)_2(iPr)_2を用い、酸素と混合させ加熱基板上に堆積させる。本研究では反応条件により膜構造(配向性、結晶粒径、膜厚)を変化させる手法の確立と膜構造と誘電率との関係を明らかにすることを目的とした。実験は基板温度600℃から750℃で蒸発器温度はPb原料130℃から165℃、Ti原料115℃から140℃、ガス流量はそれぞれPb(70sscm)、Ti(30sscm)、O2(200sscm)で行った。各成膜条件で得られたPbTiO_3膜の粒子径は膜厚の増加により大きくなるが同一温度では成膜速度に依存しない。これは2次核発生が少なく基板上の1次核の成長により膜構造が形成されるためと考えられる。また広い温度領域でPbTiO_3膜が作成でき、成膜温度を下げると結晶粒の形態が変化することが分かった。供給の際PbとTiの原料モル比をTi過剰にすると(110)、(101)面に配向した膜がPb過剰にすると(100)、(001)面に配向した膜が得られ、また、配向性は原料供給比を変化させることによりコントロールされる。誘電物性に関して、まずI-V測定測定の結果ではPbTiO_3薄膜は10^<10>〜10^<11>OMEGAcmの絶縁性であることがわかった。また誘電率の膜厚依存性を検討したところ、膜厚を4mumから1mumに薄くしていくにつれ200から100程度に減少し、基板との界面に低誘電率の層が存在することが示唆された。またCV測定においてヒステリシスが観測され、強誘電体酸化物薄膜が作成されていることが確認された。
