Title
(EN) CATALYST SUPPORT POWDER AND EXHAUST GAS PURIFYING CATALYST
(FR) POUDRE DE SUPPORT CATALYTIQUE ET CATALYSEUR DE PURIFICATION DES GAZ D'ÉCHAPPEMENT
Abstract
(EN)
The present invention provides a catalyst support powder 3 comprising ceria and zirconia, wherein the ratio of the molar fraction (mol%) of ceria on the support powder surface as measured by the X-ray photoelectron spectroscopy to the molar fraction (mol%) of ceria in the raw material is from 1.0 to 1.5. Further, the present invention provides an exhaust gas purifying catalyst 5 comprising the catalyst support powder 3 and platinum 4 supported thereon.
(FR)
La présente invention se rapporte à une poudre de support catalytique (3) contenant du cérium et de la zircone, le rapport entre la fraction molaire ( % mol) du cérium sur la surface de la poudre de support, telle que mesurée par spectroscopie de photoélectrons X, et la fraction molaire ( % mol) de cérium dans la matière brute étant compris entre 1,0 et 1,5. En outre, l'invention concerne un catalyseur de purification des gaz d'échappement (5), qui renferme la poudre de support catalytique (3) selon l'invention et du platine (4) supporté sur cette dernière.
