<p>An apparatus for removing particulate matter is provided which is able to lower a temperature to burn particulate matter. The apparatus for removing particulate matter burns and removes the particulate matter emitted from an internal combustion engine, and comprises a perovskite-type complex oxide which is represented by the general formula ABO 3 where B is a metal having a valence of +3 or more. The metal having a valence of +3 or more for B of the general formula comprises at least one metal selected from the group consisting of Ti, Zr, Hf, V, Cr, Mo, W, Mn, Fe, Ru, Co, Ni, Cu, Ag, and Au. The perovskite-type complex oxide may comprise at least one complex oxide selected from the group consisting of LaMn(III)O 3 , LaSrMn(III)O 3 , and LaCo(III)O 3 . The perovskite-type complex oxide may support Pt or Pd.</p> |
