<p>A method for preparing a decomposition catalyst for an organic halide, which comprises reacting a salt of Pt and/or Pd, an alkoxide derivative of Ti and an amino acid as an organic binding compound in a solvent, to synthesize an organic metal-containing precursor containing Ti and Pt and/or Pd in a molecule thereof, and heating the precursor to prepare the decomposition catalyst comprising fine particles of Pt and/or Pd dispersed in TiO2; and a method for manufacturing a filter for use in decomposing an organic halide, wherein the above decomposition catalyst is carried on the surface of the clean side of a ceramic filter. The method allows the uniform dispersion of fine particles of Pt and/or Pd in TiO2 particles, which results in the increase of active sites of the resultant catalyst, leading to a higher activity of the catalyst than that of a conventional catalyst. As a result, the catalyst exhibits excellent decomposition activity even at a temperature lower than 200°C.</p> |
