| titleOfInvention | Exhaust purification catalyst, exhaust purification method, and exhaust purification system |
| abstract | The present invention provides an exhaust gas purification catalyst capable of suppressing the grain growth of a plurality of fine particles. The exhaust purification catalyst of the present invention has composite metal fine particles containing Pd and Rh, and the average ratio of the total number of atoms of Rh to the total number of atoms of Pd and Rh is 0.5 atomic % or more and 6.5 atomic % or less, and X The ray wavelength is set to When the XRD analysis is performed under the condition that the diffraction surface is a Pd(111) lattice plane, the diffraction angle 2θ representing the position of the diffraction peak at the diffraction surface is determined, and by using these values, according to the formula related to Vigard's law. The value of the theoretical lattice constant B is calculated by the formula, and the value of the measured lattice constant C, and the absolute value of the difference between the theoretical lattice constant B and the measured lattice constant C are calculated according to the formulas related to Bragg's law and lattice constants. exist the following. The smaller the absolute value of the difference between the above-mentioned theoretical lattice constant B and the above-mentioned measured lattice constant C, the higher the degree of recombination of Pd and Rh with each other. |
