Abstract
Provided is: an oxidation catalyst having excellent ability to combust diesel fuel 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 particulate matter 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 precious 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 diesel fuel combustion performance is 72 kJ/mol or less.
