Abstract:
(EN) Provided is a honeycomb structure superior in combustion performance for PM and elimination efficiency for NOx. The honeycomb structure is characterized by being provided with a honeycomb structure main body 11 including zeolite and having a shape wherein a plurality of cells 12 extending from one end surface 11a to another end surface 11b in the longitudinal direction X are divided by cell walls 13, and a titanate compound supported on the surface of the cell walls 13 in the honeycomb structure main body 11, and characterized in that the titanate compound is a lepidocrocite titanate compound having a layered structure formed by a chain of TiO6 octahedrons with some of the Ti positions being substituted by one or more elements selected from Li, Mg, Zn, Ga, Ni, Cu, Fe, Al, and Mn, and ions of one or more elements selected from alkali metals exclusive of Li being coordinated between the layers in the layered structure.
(FR) L'invention concerne une structure en nid d'abeilles supérieure aux performances de combustion pour les PM et l'efficacité d'élimination des NOx. La structure en nid d'abeilles est caractérisée en ce qu'elle est pourvue d'un corps principal de structure en nid d'abeilles 11 comprenant une zéolite et ayant une forme dans laquelle une pluralité de cellules 12 s'étendant d'une surface d'extrémité 11a à une autre surface d'extrémité 11b dans la direction longitudinale X sont divisées par des parois de cellule 13, et un composé de titanate supporté sur la surface des parois de cellule 13 dans le corps principal de structure en nid d'abeilles 11, et caractérisé en ce que le composé de titanate est un composé de titanate de lépidocrocite ayant une structure en couches formée par une chaîne d'octaèdres de TiO 6 avec certaines des positions de Ti étant substituées par un ou plusieurs éléments choisis parmi Li , Mg, Zn, Ga, Ni, Cu, Fe, Al, et Mn, et des ions d'un ou plusieurs éléments choisis parmi les métaux alcalins exclus de Li étant coordonnés entre les couches dans la structure en couches.
(JA) PMの燃焼性能及びNOxの除去効率に優れたハニカム構造体を提供する。 長手方向Xに沿って、一方の端面11aから他方の端面11bに延伸している複数のセル12がセル壁13によって区画された形状を有し、ゼオライトを含む、ハニカム構造体本体11と、ハニカム構造体本体11におけるセル壁13の表面に坦持されている、チタン酸塩化合物とを備え、チタン酸塩化合物が、TiO八面体の連鎖により形成される層状構造を有し、Ti席の一部がLi、Mg、Zn、Ga、Ni、Cu、Fe、Al及びMnから選ばれる1種又は2種以上の元素で置換され、層状構造における層間にLiを除くアルカリ金属から選ばれる1種又は2種以上の元素のイオンが配位したレピドクロサイト型チタン酸塩化合物であることを特徴とする、ハニカム構造体。
