     More details

    エネルギー、環境に関する様々な先端技術において重要な基礎となる繊維状機能性炭素材の新規構造概念構築と応用拡充に尽くすと共に、その原理を共有する材料技術の効用実行を主に行っている。繊維状機能性炭素材は炭素六角網面(グラフェン)の積層体(クラスター)の集合からなる多結晶体である。特に、クラスター集合が形成する「メゾ/ミクロ単位の微細組織」に関心を持ち、TEM、SEMとSTMを併せて駆使することで、新規3次元構造モデルのヒエラルキ的構築とそれに基づいた構造と物性の相関を探る研究を行い、物性の改善と新規物質の開発を行ってきた。繊維状機能性炭素材のナノ/メゾ/ミクロのヒエラルキ的構造認識と構造と物性の相関の観点から他の多様な人造黒鉛の物性発現機構を理解すると共に、その理解からより物性が改善された機能性炭素材の創製との効用を行ってきている。
    ②本件技術(研究)の特徴、従来技術との相違等
    ・ 従来、繊維状機能性炭素材は、グラフェン分子の積層によるバルクとして認識されており、液晶ピッチ系炭素繊維の低圧縮強度、等方性炭素繊維の低強度および多層炭素ナノチューブの高抵抗・低強度 等についてその理由が解明できなかった。
    ・ 候補者は、こうした人造黒鉛構造認識(グラフェン積層→人造黒鉛バルク)を、クラスター集合が形成する「微細組織」を見出すことにより、ナノ(クラスター)/メゾ(ミクロドメイン)/ミクロ(ドメイン)/マクロ(バルク)構造のヒエラルキ的構造として認識し、その制御技術をベースにした繊維状炭素材の創製と効用を行ってきた。液晶ピッチ系炭素繊維や多層炭素ナノチューブを形成するドメイン節が低伸び率(低圧縮強度)や高抵抗の原因であることをわかり、より小さなドメインの螺旋的配向を持つ等方性ピッチ系炭素繊維のグラフェン配向性を改善させることで日2倍高強度を実現し、自動車車体用炭素繊維の実現を行っている。
    従来炭素ナノ繊維はグラフェンの単純積層構造として認識されていたが、単位構造(炭素ナノ繊維素)で形成されていることを実証し、物質特許を獲得している。

    A conventional porous carbon is still a very promising material for the removal of gaseous pollutants because of its abundant surface functional groups and a high specific surface area. Here, we prepared an environment-friendly uniform N-rich narrow micropore activated carbon, for the removal of formaldehyde, based on steam activation and N-rich with chitin as the starting material. A sample carbonized at 500 °C and steam activated at 800 °C (CAC800) showed a reasonable yield (55%) with uniform and narrow micropores without mesopores but having a balanced nitrogen functionality. CAC800 possesses outstanding formaldehyde removal capabilities under both dry and wet (humidity 45%) conditions. In addition, when compared with commercial activated carbon materials, we clearly demonstrated that the existence of high nitrogen content with uniform and narrow micropores simultaneously removed formaldehyde, effectively.

    Adsorption heat pumps (AHPs) have been envisioned to be the next generation of cooling systems owing to their low electricity consumption and negligible total equivalent warming impact (TEWI). This study investigated the adsorption characteristics, thermodynamic properties, and environmental impact of HFC32 onto six waste mangrove-derived activated carbons (MACs), which were synthesized at various operating conditions. Adsorption isotherms were acquired below and above critical temperatures (30, 50, 70, and 90 °C) by a high-precision thermogravimetric analyzer (TGA). Notably, the most promising sample exhibited a remarkable HFC32 adsorption capacity (2.628 kgref per kgads), which is a benchmark for any HFC/AC pair to date. Six sets of isotherm data were fitted with well-established Dubinin-Astakhov (D–A) and Tóth equations, resulting in a notably high goodness of fit. The isosteric heat of adsorptions was also assessed and elucidated using the ideal Clausius-Clapeyron model and modified non-ideal models proposed by Rahman et al. and Chakrabarty et al. Furthermore, a comprehensive thermodynamic and ecological footprint analysis, including the specific cooling effect (SCE), coefficient of performance (COP), Clapeyron analysis, and total equivalent warming impact (TEWI) assessment, were conducted. The implementation of the aforementioned MAC/HFC pair can potentially achieve an SCE of 457 kJ kgads–1 for space cooling and approximately 25% reduction in CO2 emissions. Adsorption uptake, SCE, COP, and TEWI analyses collectively emphasize the significant potential of pairing MACs with HFC32 in designing an environmentally sustainable AHP.

    This study involved the heterogenization of a binder pitch (BP) using a small amount of nanocarbon to improve physical properties of the resulting graphite electrode (GE). Heterogenization was carried out by adding 0.5–2.0 wt.% platelet carbon nanofiber (PCNF) or carbon black (CB) to a commercial BP. To evaluate the physical properties of the BPs, we designed a new model graphite electrode (MGE) using needle coke as a filler. The heterogenized binder pitch (HBP) with PCNF or CB clearly increased the coking value by 5–13 wt.% compared to that of the as-received BP. Especially, the model graphite electrodes prepared with HBPs containing 1.0 wt.% PCNF or CB showed significantly improved physical properties compared to the control MGE from the as-received BP. Although the model graphite electrodes prepared with HBPs showed similar properties, they had smaller pore sizes than the control. This indicates that heterogenization of the BP can effectively decrease the pore size in the MGE matrix. Correlating the average pore sizes with the physical properties of the model graphite electrodes showed that, for the same porosity, matrices formed by the HBP with a smaller average pore size can effectively improve the apparent density, tensile strength, and oxidation resistance of the model graphite electrodes.

    Petroleum residues are produced as by-products of petroleum refining. Recently, various effective non-fuel uses of petroleum residues have been considered toward a carbon-neutral society. Pyrolysis fuel oil (PFO) is one of the petroleum residues. Advanced utilization of PFO for future non-combustion applications is required. In this study, Mesophase pitch-based carbon fibers (MPCF) were successfully produced from PFO. Spinnable mesophase pitch (SMP), a precursor of MPCF, was prepared using PFO as a raw material through the pressurized heat treatment at 420°C-430 °C. PFO is from the naphtha catalytic cracking process for ethylene production and is mainly composed of 2–4 condensed polycyclic aromatic hydrocarbons (PAHs). The high temperature pressurized heat treatment could result in the PFO-derived SMPs with yield of 23.0 wt% and excellent spinnability. On the other hand, without pressurized heat treatment, the yield was 8.5 wt%. This indicates that pressurized heat treatment significantly contributed to the yield improvement. In addition, the preference for the conversion of PFO molecules into highly condensed PAHs via cata-condensation during pressurized heat treatment at 420°C-430 °C was observed, which may be the main reason for the high yield and excellent spinnability of the resulting SMPs. As a result, the obtained PFO-derived SMPs though the such high-temperature pressurized heat treatment provided the typical radial-random transversal textures and general mechanical performances of MPCF: The tensile strength and Young's modulus of the PFO-derived MPCF graphitized at 2400 °C showed high values of 1.9–2.7 GPa and 554–635 GPa, respectively.

    Analysis of the heavy fractions in crude oil has been important in petroleum industries. It is well known that heavy fractions such as vacuum gas oils (VGOs) include heteroatoms, of which sulfur and nitrogen are often characterized in many cases. We conducted research regarding the molecular species analysis of VGOs. Further refine processes using VGOs are becoming important when considering carbon recycling. In this work, we attempted to classify compounds within VGOs provided by Kuwait Institute for Scientific Research. Two VGOs were priorly distillated from Kuwait Export crude and Lower Fars crude. Quantitative analysis was performed mainly using matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOFMS). MALDI-TOF-MS has been developed for analyzing high-molecular-weight compounds such as polymer and biopolymers. As matrix selection is one of the most important aspects in MALDI-TOFMS, the careful selection of a matrix was firstly evaluated, followed by analysis using a Kendrick plot with nominal mass series (z*). The objective was to evaluate if this work could provide an effective classification of VGOs compounds. The Kendrick plot is a well-known method for processing mass data. The difference in the Kendrick mass defect (KMD) between CnH2n−14S and CnH2n−20O is only 0.0005 mass units, which makes it difficult in general to distinguish these compounds. However, since the z* value showed effective differences during the classification of these compounds, qualitative analysis could be possible. The analysis using nominal mass series showed the potential to be used as an effective method in analyzing heavy fractions.

    <p>In the pursuit of carbon neutrality, marine biomass (MB) has emerged as a promising alternative to traditional carbon sources. This study endeavors to establish an economically viable pathway to derive porous carbon materials from MB. Simple pyrolysis of MB resulted in a MB-based carbon (MBC) characterized by a negligible open-pore structure. However, subsequent water washing transformed it into a porous material. N<sub>2</sub> adsorption tests revealed that the pyrolysis temperature and washing method substantially influenced the specific surface area (SSA) and pore volume of the MBC. While the catalytic activation function of elements inherent in MB, such as Na, Mg, K, Ca, and Cl, rendered MBC inherently porous, these elements also induced an initial pore-blocking effect that concealed the pores. Subsequent washing with water nearly eradicated Na, K, and Cl from MBC, making a number of the concealed pores accessible. Furthermore, a CO<sub>2</sub> aeration washing method effectively eliminated Mg and Ca elements from MBC, resulting in a substantial increase in SSA (>1000 m<sup>2</sup>/g) without the need for additional activation processes. Based on an understanding of the dual role of the elements naturally present in MB, this study demonstrates a potential strategy for environmentally friendly and cost-effective porous carbon production.</p>

    Pyrolysis of marine biomass (MB) to create marine biomass-derived carbon materials (MBCs) for industry is a sustainable solution. In this study, we systematically examined pyrolysis processes and performed elemental composition analyses of MB and MBC. The results revealed that MBC contained 12.5–25.5 mass% of alkali and alkaline earth metals (AAEMs). As the pyrolysis temperature increased, some of these AAEMs underwent physical phase changes. Subsequently, we applied CO2 aeration washing for the first time or low-concentrated acetic acid washing to eliminate AAEMs from MBC, reducing potential hazards in the future industrial application. Characterization results suggested that both post-processes effectively removed AAEMs from MBC, reducing the average content of Na and K to 0 mass%, Ca to 1.4 mass%, and Mg to 1.9 mass%. The Cl content was also reduced to 0.1 mass%. After removing AAEMs, the final carbon content of MBCs was as high as 90.8 mass% (dry ash free basis) with a minimum ash content of 6.4 mass% (dry basis) according to ultimate analysis. Comparison with commercial coal products showed that carbon contents were superior and ash contents were lower than those of most coal samples, suggesting that the treated MBCs are of sufficient quality for the carbon cycle industry.

    Electric double-layer capacitors (EDLCs) afford long cycle life and high-power density by dielectric ion adsorption and desorption on the surface of porous materials. However, high potential charges/discharges lower the capacitance of EDLCs. In this study, we quantitatively evaluated the large pore-size effect of activated carbons (ACs) on the electric double layer capacitances at various voltages based on a hierarchical domain model from a structural point of view. ACs with highly developed microporous and mesoporous (2–4 nm) structures were prepared using KOH activation. The AC with small amount of mesopores showed a specific capacitance of 30.35 F/g at a voltage of 2.7 V, where it significantly lowered to 20.93 F/g at a high voltage of 3.3 V. Meanwhile, the highly microporous AC with abundant mesopores had a higher specific capacitance (40.77 F/g at 2.7 V to 38.22 F/g at 3.3 V). 19F-NMR results indicate that the amounts of solvated ions in the mesopores significantly increased in all the ACs after charging at a higher voltage. The mitigation of the high-voltage capacitance drop might occur because of the mesopore structure that functions as a buffer space for the electric double layer.

The state and structure of adsorbed and/or intercalated molecules and ions on/in the carbon materials can also be determined using this method. Eddy currents induced by the magnetic field during measurements cause a temperature increase in conducting carbon materials. The effects of various physical and chemical characteristics of the carbon materials on this temperature increase were investigated. The oxygen content was found to be the dominant factor determing the temperature increase, with a higher oxygen content giving a smaller temperature increase. This correlation enables a rough estimate of the temperature increase in carbon materials prior to performing MAS-SS-NMR measurements.</p>

    As the demand for artificial graphite for lithium-ion battery (LIB) anode materials is on the rise, technologies for optimizing the manufacturing processes and reducing the production costs of artificial graphite are crucial. At the same time, globally, regulations on the generation of harmful volatile substances during the artificial graphite production process are also becoming increasingly stringent. In this study, we focused on a continuous kneading process that minimizes the emission of volatile substances during the manufacturing of artificial graphite. To this end, a carbonized material was first prepared from a mixture of needle coke and binder pitch and processed at 3200 °C using two types of co-rotating twin-screw extruder-based continuous kneading equipment to ultimately obtain artificial graphite. The physical properties of the carbonized as well as graphitized materials were analyzed, which revealed the superior performance of the LIB anode material, namely a discharge capacity of greater than or equal to 350 mAh/g, and an initial efficiency of 91% or higher. Thus, a continuous kneading manufacturing process that emits less harmful volatile substances and provides artificial graphite with sufficient battery performance was demonstrated.

    Acetaldehyde (CH3CHO) in the atmosphere is associated with adverse health effects. Among the various options for use in removing CH3CHO, adsorption is often employed because of its convenient application and economical processes, particularly when using activated carbon. In previous studies, the surface of activated carbon has been modified with amines to remove CH3CHO from the atmosphere via adsorption. However, these materials are toxic and can have harmful effects on humans when the modified activated carbon is used in air-purifier filters. Therefore, in this study, a customized bead-type activated carbon (BAC) with surface modification options via amination was evaluated for removing CH3CHO. Various amounts of non-toxic piperazine or piperazine/nitric acid were used in amination. Chemical and physical analyses of the surface-modified BAC samples were performed using Brunauer–Emmett–Teller measurements, elemental analyses, and Fourier transform infrared and X-ray photoelectron spectroscopy. The chemical structures on the surfaces of the modified BACs were analyzed in detail using X-ray absorption spectroscopy. The amine and carboxylic acid groups on the surfaces of the modified BACs are critical in CH3CHO adsorption. Notably, piperazine amination decreased the pore size and volume of the modified BAC, but piperazine/nitric acid impregnation maintained the pore size and volume of the modified BAC. In terms of CH3CHO adsorption, piperazine/nitric acid impregnation resulted in a superior performance, with greater chemical adsorption. The linkages between the amine and carboxylic acid groups may function differently in piperazine amination and piperazine/nitric acid treatment.

    Mesophase pitch is a unique graphitizable material that has been used as an important precursor for highly graphitic carbon materials. In the current study, we propose to consider a spinnable mesophase pitch as a lyotropic liquid crystalline solution composed of solvent components and liquid crystalline components, so-called mesogen or mesogenic components. Among mesophase pitches, the supermesophase pitch is defined as a mesohpase pitch with 100% anisotropy, and can only be observed in pitches with a proportion of mesogenic components exceeding the threshold concentration (TC). We also examined the critical limit of AR synthetic pitch and 5 experimental spinnable mesophase pitches (SMPs). Then, we examined the effect of the solvent component on the minimum required amount of mesogenic component using a selected solvent component instead of their own solvent components. AR pitch showed 100% anisotropy with the least amount of its mesogenic component, THF insoluble components, of 60 wt.%. The solvent component, THF soluble components, extracted from AR-pitch, which has a molecular weight pattern similar to that of the original material but more amount of naphthenic alkyl chains, showed better solvent functionality than those of other THF solubles (THFSs) from other as-prepared spinnable mesophase pitches. This is why a lower amount of AR THFS can produce a supermesophase pitch when combined with the THFI (mesogenic components) of other experimental mesophase pitches. As a result of the current analysis, we define the mesogens as molecules that not only readily stack, but also maintain stacking structures in a fused state in the solution. The solvent component, on the other hand, is defined as molecules with a structure that readily decomposes in a fused state in the solution.

    Spinnable mesophase pitch (SMP) is an important graphitizable precursor for high-performance carbon materials. Generally, SMPs show fully developed anisotropic texture, and the pitches contain isotropic contents more than 30 wt%, which plays the role of solvent for the mesogenic components in the lyotropic liquid crystalline system of the pitch. Here, we prepared SMP by blending the mesogenic components of AR mesophase pitch with various isotropic pitches to evaluate the usability of isotropic pitches as solvents. The mesogenic components were prepared by tetrahydrofuran fractionation of AR mesophase pitch. Isotropic pitches with a softening point of 140–220 °C were prepared separately by simple heat treatment of slurry oil (SO) and coal tar pitch (CTP). SMPs were prepared by thermal blending of the above mentioned mesogenic components and isotropic pitches in various blending ratios. CTP-derived isotropic pitch showed better solvent performance than a SO-derived pitch in terms of anisotropic texture. SMP prepared by blending of the mesogenic components and CTP-derived isotropic pitch with a softening point of 180 °C at the ratio of 4/6 (w/w) showed almost 100% anisotropic texture; the carbon fiber derived from the pitch showed tensile strength of 2.7 GPa and Young's modulus of 470 GPa after graphitization at 2,800 °C.

    <p>This review explores recent research regarding mesophase pitch (MP). Spinnable mesophase pitch (SMP) was used as a model pitch for MP in all experiments. We explain some phenomenological results of the lyotropic liquid crystalline properties of the SMP, which show that the MP behaves as a typical lyotropic liquid crystal. The mesogenic and solvent components of SMP are defined. We define the threshold concentration (TC) as the minimum amount of mesogenic component necessary for SMP to achieve 100 vol% anisotropy. We also report the TCs of various SMPs and discuss the effects of the solvent component. Concerning the identity of the mesogenic component, we discuss quantitative correlations between the size of the layered molecular stacking units and the anisotropic content of the SMP. Research has shown that a layered molecular stacking unit larger than a specific size corresponds to the mesogenic component of the MP. We discuss a novel method for the manufacture of SMPs using our understanding of MP as a lyotropic liquid crystal, which comprises thermal mixing of optimal amounts of the mesogenic and solvent components that were prepared separately under different conditions. This method enables the properties of each component to be optimized without involving a costly hydrogenation process. Finally, we discuss how this approach can be used to increase SMP yield by modifying the contents of the anisotropic mesogenic and solvent components.</p>

    The correlation of the anisotropic texture and (002) the molecular stacking property of spinnable mesophase pitch (SMP) was closely examined. SMP was found to be a specific solution consisting of mesogenic and solvent components, and the mesogenic component was composed of a cluster unit of (002) stacked molecular sheets. The anisotropic texture of SMP was strongly correlated with the height of (002) molecular stacking. When the concentration ratio of the mesogenic component to the solvent component was higher than the threshold concentration, the SMP always had 100 vol% anisotropic texture and a similar or larger number of stacked (002) sheets compared with its mesogenic component in both the solid and molten states. The solvent component, in both lamellar and hexagonal phases, assisted orientation of mesogenic molecules and rearrangement of mesogenic cluster units, thereby inducing a higher degree of graphitization than that of the solvent-free mesophase pitch. A schematic phase model of SMP was proposed based on a lyotropic liquid crystalline system and a hierarchical domain model.

    Activated carbon is a suitable adsorbent for adsorption heat pumps (AHPs) with ethanol refrigerants. Although chemically activated carbon with highly developed pore structures exhibits good ethanol adsorption, the associated high production costs inhibit its practical application as an AHP adsorbent. Moreover, although physical activation can produce inexpensive activated carbon, the limited pore development limits the ethanol uptake. Recently, we developed a pressurized physical activation method that can produce activated carbon with a well-developed pore structure and characteristic pore size distribution. In this study, we investigated the applicability of the pressurized physically activated carbon as an adsorbent in activated carbon-ethanol AHP systems. Because of the large number of pressurization-induced pores of appropriate size, the pressurized physically activated carbon showed effective ethanol uptake comparable with that of chemically activated carbon on a weight basis. Furthermore, on a volume basis, the pressurized physically activated carbon, with a high bulk density, showed much higher effective ethanol uptake than chemically activated carbon. These results confirm the potential of the pressurized physically activated carbon as a relatively inexpensive high-performance adsorbent for AHP systems with ethanol refrigerants. This journal is

  • Specific Heat Capacity of Carbon-Based Composites for Adsorption Heat Pump and Desalination Applications

    Rocky K.A., Islam M.A., Pal A., Saha B.B., Kil H.S., Yoon S.H., Miyawaki J.

    Springer Water  2022    ISSN:23646934

     More details

    Environmentally benign adsorption heat pump (AHP) and desalination (AD) systems have already attracted considerable attention for space cooling/heating and potable water production since they require no electricity and are driven by solar or waste heat. The adsorbent material is the key element of these adsorption systems. Highly porous carbon-based consolidated composites are very promising adsorbents. Specific heat capacity (cp) of adsorbent is one of the most significant thermophysical properties. It plays a vital role in predicting the performance of the systems accurately. However, the estimation of the cp of adsorbent materials is a demanding issue and has not been focused sufficiently yet. Therefore, this chapter will present the significance of specific heat capacity, detailed experimental procedure, and the cp of composites, as well as the parent materials at the operating temperature range of AHP and AD systems. Finally, all the experimental data are analyzed rigorously and correlated with the established equations of cp. The presented experimental cp data along with the fitted parameters are crucial in the design of AHP and AD systems.

    高機能性炭素材は従来の黒鉛,コークス,活性炭,カーボンブラック,黒鉛電極をはじめ,最近のリチウムイオン電池用負極材や炭素ナノチューブやグラフェンなどのナノ炭素材に至るまで多様な組成や構造の炭素材で構成される.日本は高機能性炭素材の製造と応用において技術や価格の両面で世界をリードする炭素先進国である.こうした高機能性炭素材は天然黒鉛以外すべて人造カーボンであり,有機系原料の熱処理によって形成される炭素六角網面(グラフェン)の積層した構造からなる.炭素材は一般的に有機物質から調製されるが,低コストなため,石炭,石油,バイオマス,およびその誘導体であるガス,タール,ピッチ,コークスやチャーなど炭素材と類似な分子構造を持つ原料が一般に用いられる.こうした原料は炭素以外の酸素,窒素,硫黄等のヘテロ元素と共に多様な無機物を含んでおり,これらは炭素材の製造過程で様々な官能基と不純物として残存し,製品の炭素材の物性に影響する.
    本発表では,こうしたヘテロ元素の中でも窒素官能基の種類が炭素材の機能性に及ぼす影響とそれを利用した機能性炭素材の調製について例を示しながら紹介する.窒素は化石燃料やバイオマスを構成する重要な元素であり,炭素とは異なる分子構造をもたらすため,機能性炭素材において特有の官能基として機能する.炭素材の中で窒素原子が含まれた官能基を有する材料を窒素ドープ炭素と呼び,微量の不純物を添加する一般的なドーピングに対し,機能性を高めるためにわざわざ多量の窒素を含有する材料も利用されている.窒素ドープ炭素の製造は,原料に窒素を含む化合物を用いるか合成系中に窒素分を共存させて行う.
    図1に示したように炭素六角網面に窒素原子が入り込むことで,π電子系に影響が及ぼされ,ピリジン型窒素の塩基性誘因やグラファイト型窒素の正帯電などの現象が起こるとされている1).このような電子状態の変化により,酸素還元反応を始めとした種々の触媒活性や電気化学的諸特性の向上が報告されているが2, 3),本発表では代表的なインドア大気汚染物質のであるホルムアルデヒド(HCHO)シックハウスガスの吸着・除去における窒素官能基の影響,そしてその問題点と解決手法について説明する.

    紡糸用メソフェーズピッチは炭素繊維,電池用負極材等に重要な前駆体として期待されている.本研究では可溶性石商ピッチをリオトロピック液晶の観点から把握し,水素供与性・受容性を有する溶媒分子と分子積層性を有する溶質、メソゲンでメソフェーズピッチは構成されていると考え、メソゲンが過剰に存在する場合、異方性組織は発現するが、溶融解ができず、異方性コークスが生成され、溶媒分子が過剰に存在する場合、溶融解はできるが、異方性組織が発現せず、等方性ピッチが生成される。つまり、メソゲン濃度がある濃度以上のとき、メソフェーズ特性が生じることを明確にした。こうした研究によって可溶性液晶ピッチの収率向上と共に物性改善の重要な手法を提案することになった.

    TiO2 (anatase phase) nano-particle entrained carbon nanofiber (CNF) was successfully prepared through the low temperature impregnation of titanium tetrachloride onto specially prepared tubular type CNF (TCNF) with nano-gate for the application as anode materials for Li-ion and Na-ion batteries. TCNF which has lots of nano-gated channels on the surface could incorporate about 32 wt% of nano-sized TiO2 particles inside of the tube. The obtained TiO2 entrained TCNT (TiO2/TCNF) showed a large discharge capacities of 320 mAh/g and 120 mAh/g compared to those of bare TiO2 in both of the Li-ion and Na-ion battery systems, respectively.

    We have examined the influence of raw materials mixing on volume of closed pores of resulted carbon materials. In this study, we used the three aromatic compounds of naphthalene, anthracene and pyrene with a cross-linking agent for obtaining cokes with different closed pores. The closed pore volume of prepared carbon materials was calculated from the difference between true and apparent densities. From the results, carbon materials derived from smaller ring membered compound (naphthalene) based coke showed larger volume of closed pore compared to anthracene and pyrene based ones. The size of closed pore in carbon materials is now investigating.

    Surface and pore structural properties of carbon materials were investigated by applying the solid-state NMR method using water as a molecular probe. By using two series of carbon materials, non-porous and porous, having different amounts of surface functionalities and similar external surface area or porosity, it was found that influence rate of surface functionalities is different between water molecules adsorbed on the external surface and those in micropores.

    To develop high performance activated carbons for adsorption heat pumps, it is important to understand adsorption behaviors of the refrigerant molecules in pores of the activated carbons. Not only pore structures, such as pore size and shape, but also surface functionalities strongly influence on the adsorption behaviors especially for polar molecules such as water and ethanol, which are typical refrigerants for the adsorption heat pump. In this study, we tried to evaluate influences of surface functionalities on adsorption behavior of ethanol molecules in pores by solid-state NMR technique, which is one of powerful tools to investigate states of molecules adsorbed in pores.
