Abstract
A catalyst for the purification of exhaust gas that can be used to highly efficiently treat an exhaust gas which has moisture and fluctuates between an oxidizing atmosphere and a reducing atmosphere even after the catalyst is exposed to a high temperature is provided. The present invention relates to a catalyst for the purification of exhaust gas having a catalyst layer of catalyst components comprising a noble metal, magnesium oxide, and a refractory inorganic oxide formed on a three-dimensional structure, wherein the catalyst layer has two peaks originated from the magnesium oxide in a pore distribution obtained by mercury intrusion technique.
