Abstract

The present invention relates to an oxidation catalyst, a method for preparing the same, and a filter for exhaust gas purification comprising the same and, more specifically, to an oxidation catalyst, a method for preparing the same, and a filter for exhaust gas purification comprising the same, the oxidation catalyst being formed by comprising an amorphous metal alloy powder, thereby being preparable at a low cost, being capable of enhancing purification efficiency for exhaust gas when applied to the filter for exhaust gas purification, and being capable of deriving reliability enhancement for operation of an exhaust gas purifier having the filter for exhaust gas purification mounted therein. To this end, the present invention provides an oxidation catalyst, a method for preparing the same, and a filter for exhaust gas purification comprising the same, the oxidation catalyst characterized by being coated onto the carrier surface of the filter for exhaust gas purification and being formed by comprising an amorphous metal alloy powder.
