CATALYST FOR EXHAUST GAS PURIFICATION, METHOD FOR PRODUCING SAME, AND EXHAUST GAS PURIFICATION METHOD USING SAME

The purpose of the present invention is to provide: a catalyst with which it is possible to efficiently purify HC, CO, and NOx included in exhaust gas; a method for producing the same; and an exhaust gas purification method using the same. A catalyst for exhaust gas purification which has at least two layers comprising a lower catalyst layer and an upper catalyst layer on a fire resistant three-dimensional structure, wherein the lower catalyst layer and the upper catalyst layer each independently include precious metal, alumina, and a cerium-zirconium composite oxide, and at least a portion of the upper catalyst layer includes a pore connecting substance that has a combustion decomposition temperature of 150 to 400 deg C, a precious metal precursor, alumina, and cerium-zirconium composite oxide, said catalyst for exhaust gas purification being formed by a production method that includes the steps of applying, on the lower catalyst layer, an upper catalyst layer forming slurry which has a content rate of the p
