PURPOSE: A low temperature activating catalyst for a vessel exhaust gas filter, a method for manufacturing the same, and the vessel exhaust gas filter are provided to prevent the purifying performance reduction of nitrogen oxide due to the reduction of catalyst sites by the lapse of time. CONSTITUTION: A low temperature activating catalyst(20) for a vessel exhaust gas filter includes 1 to 3 weight% of copper and 5 to 20 weight% of aluminasol based on FeZSM5, a zeolite support. Manganese and calcium are capable of being further included in the catalyst. The aluminasol is sol with a single component-based needle structure. A method for manufacturing the catalyst includes the following: deionized water and a copper precursor are stirred; the stirred product is stirred with FeZSM5 such that the content of the copper becomes 1 to 3 weight% of based on the FeZSM5; the secondary stirred product is stirred with 5 to 20 weight% of aluminasol based on the FeZSM5. |
