Abstract: PURPOSE: A catalyst for a diesel particulate filter, a method for manufacturing the same, a smoke reducing apparatus for diesel vehicle including the same are provided to maintain the high activity of the catalyst for a long period of time regardless of high temperature or vulcanization condition by using a silica-carried platinum-neodymium alloy. CONSTITUTION: A catalyst for a diesel particulate filter includes a silica-carried platinum-neodymium alloy. The molar ratio of the platinum and the neodymium in the alloy is 1:0.1 to 1:1.2. The content of the platinum in the total weight of the catalyst is between 0.1 and 10 weight%. One H_2-temperature programmed reduction peak of the catalyst is in a range between 400 and 800 degrees Celsius. A method for manufacturing the catalyst includes the following: A platinum precursor and a neodymium precursor are mixed in an aqueous solution. The mixture is carried in silica. The silica-carried mixture is plasticized at a temperature between 300 and 600 degrees Celsius. In the plasticizing process, a platinum-neodymium alloy is formed and the alloy is fixed to the silica.
