Abstract:
(EN) A high-contact structure for solid particles which comprises aggregates formed by the primary aggregation of primary particles made of a metal and/or metal oxide and the secondary aggregation of the primary-aggregation product, wherein the primary particles have an average particle diameter of 1-100 nm. In the pores formed by the primary-aggregation product, the volume of pores having a pore diameter in the range of [(average pore diameter of the pores)±50%] accounts for 60% or more of the total volume of the pores. This high-contact structure for solid particles can efficiently trap a wide range of solid particles including carbon-containing ingredients such as soot and PMs having a small particle diameter. It is extremely useful as an oxidation catalyst, etc.
(FR) La présente invention concerne une structure à contact fort pour particules solides qui comprend des agrégats formés par l'agrégation primaire de particules primaires faites d'un métal et/ou d'un oxyde de métal et l'agrégation secondaire du produit provenant de l'agrégation primaire, les particules primaires ayant un diamètre moyen de particules allant de 1 à 100 nm. Dans les pores formés par le produit de l'agrégation primaire, le volume de pores ayant un diamètre de pore dans la gamme du [(diamètre moyen depore des pores) ± 50 %] représente 60 % ou plus de volume total des pores. Cette structure à contact fort pour particules solides peutpiéger de manière efficace une large gamme de particules solides comprenant des ingrédients contenant du carbone tels que la suie et des PM ayant un petit diamètre de particules. Elle est extrêmement utile en tant que catalyseur d'oxydation, etc.
