摘要：Provided is: an oxidation catalyst having excellent ability to combust light oil intermittently sprayed from a nozzle disposed in an exhaust pipe, the oxidation catalyst being incorporated into an exhaust gas purification device having a diesel particulate filter (DPF) or a catalyst soot filter (CSF) for collecting micro-particulate components from a diesel engine; and an exhaust gas purification device that uses the oxidation catalyst. An oxidation catalyst for exhaust gas purification in which a noble metal component is carried on an inorganic matrix, wherein the inorganic matrix is one or more inorganic oxides selected from the group consisting of alumina, titania, zirconia, silica, and silica-alumina, the oxidation catalyst being characterized in the use of a material in which the activation energy of light-oil combustion performance is 72 kJ/mol or less.
