Abstract
(EN) A carbon material for use as a catalyst carrier is provided. When used as a catalyst carrier, the carbon material exhibits high chemical stability, electrical conductivity and excellent durability while keeping high porosity, and can attain excellent diffusion of a reaction raw material and a reaction product. This carbon material is characterized by: consisting of a carbon mesoporous dendrite body having a three-dimensional structure where rod- or ring-shaped, carbon-containing bodies are linked to each other in a branched state; having a pore diameter of 1 to 20 nm and a cumulative pore volume of 0.2 to 1.5cc/g as determined by analyzing a nitrogen adsorption isotherm by the Dollimore-Heal method; and exhibiting, in the powder X-ray diffraction spectrum, a peak corresponding to a diffracted ray assignable to the (002) plane of graphite at a diffraction angle (2θ: degree) between 20 to 30 degrees and a peak having a half width of 0.1 to 1.0 degree at 25.5 to 26.5 degrees.
(FR) L'invention concerne une matière de carbone en vue d'une utilisation comme support de catalyseur. Lorsqu'elle est utilisée comme support de catalyseur, la matière de carbone présente une stabilité chimique élevée, une conductivité électrique élevée et une excellente durabilité tout en conservant une porosité élevée, et peut atteindre une excellente diffusion d'une matière première de réaction et d'un produit de réaction. Cette matière de carbone est caractérisée en ce que : elle consiste en un corps de dendrite mésoporeux de carbone ayant une structure tridimensionnelle où des corps contenant du carbone, en forme de tige ou d'anneau sont liés les uns aux autres dans un état ramifié ; elle a un diamètre de pore de 1 à 20 nm et un volume de pore cumulé de 0,2 à 1,5 cm3/g tel que déterminé par analyse d'une isotherme d'adsorption d'azote par la méthode Dollimore-Heal ; et elle présente, dans le spectre de diffraction des rayons X sur poudre, un pic correspondant à un rayon diffracté pouvant être assigné au plan (002) de graphite à un angle de diffraction (2θ : degré) entre 20 et 30 degrés et un pic ayant une largeur à mi-hauteur de 0,1 à 1,0 degré à 25,5 à 26,5 degrés.
(JA)  触媒担体として用いたとき、高い気孔性を保持しつつ、化学的に安定で、電気伝導性を有し、耐久性に優れ、かつ、反応原料および反応生成物の拡散性にも優れた触媒担体用炭素材料を提供する。 炭素を含む棒状体または環状体が枝分かれした三次元構造を有する樹状の炭素メソポーラス構造体から成り、窒素吸着等温線をDollimore-Heal法で解析して求まる細孔径1~20nm及び積算細孔容積0.2~1.5cc/gを有し、粉末X線回折スペクトルが、回折角(2θ:度)20~30度の間に、グラファイトの002回折線相当のピークを有し、且つ25.5~26.5度に半値幅が0.1度~1.0度のピークを有することを特徴とする。
