Process for producing organic halogen compound-decomposing catalysts, and a process for producing organic halogen compound-decomposing filters

Abstract

An organic halogen compound-decomposing catalyst is provided, which affords excellent decomposing percentages even at low temperatures, and reduces the possibility of re-synthesizing dioxins and brominated dioxins. An organic halogen compound-decomposing catalyst is obtained by reacting a Pt salt and/or a Pd salt, an alkoxide derivative of Ti compound and an amino acid as an organic binder in a solvent, thereby synthesizing an organic metal precursor containing Pt and/or Pd and Ti in molecules thereof, and heating the organic metal precursor. This catalyst may be carried on a surface of a clean side of a ceramic filter. Since active points can be increased by uniformly dispersing the Pt and/or Pd particles in Ti particles, the catalyst has higher activity as compared with conventional catalysts, and exhibits excellent decomposing effects even at temperatures lower than 200° C.
