| titleOfInvention | Exhaust gas purification catalyst carrier, exhaust gas purification catalyst using the same, and method for producing exhaust gas purification catalyst carrier |
| abstract | PROBLEM TO BE SOLVED: To provide a catalyst carrier for exhaust gas purification useful as a catalyst carrier that provides a catalyst that realizes a high level of catalytic activity even when a transition metal compound is used as a supported catalyst component, and for that purpose, alumina is used. To provide a method capable of producing an exhaust gas purifying catalyst carrier in which ultrafine particles containing and ultrafine particles containing ceria are uniformly mixed with extremely high dispersibility. An exhaust gas purifying catalyst carrier comprising a mixture of first ultrafine particles containing alumina and second ultrafine particles containing ceria, All metal elements contained in the carrier in an amount of 0.1% by mass or more are analyzed by energy dispersive X-ray spectroscopy using a scanning transmission electron microscope with a spherical aberration correction function. The first ultrafine particles and the second fine particles are so satisfied that the standard deviation of the content of each metal element obtained by measuring the content (mass%) at 300 measurement points is 10 or less. Ultra fine particles are uniformly dispersed, The specific surface area determined by the BET method is 110 m 2 / g or more, An exhaust gas purifying catalyst carrier, wherein the second ultrafine particles have an average crystallite diameter of 5 to 11 nm determined by an X-ray diffraction method.
