An adsorbent having the capability of decomposing an organic halogen compound, which adsorbent cannot only adsorb organic halogen compounds contained in waste gases but also can assuredly decompose them without synthesizing them as well as a process for producing the same are provided. A salt of Pt and/or Pd, an organic titanium compound and an organic binder are reacted in a solvent, to thereby synthesize a dispersion of an organic metal compound precursor containing Pt and/or Pd and Ti in molecules thereof, a sol of TiO2 is added to the dispersion to prepare a catalyst-coating solution, an activated carbon is impregnated with the catalyst-coating solution, and the resulting mixture is heated, thereby allowing the activated carbon to carry thereon an organic halogen compound-decomposing catalyst comprising TiO2 and, dispersed therein, fine particles of Pt and/or Pd. In a low temperature range of 130 to 150° C. in which the activated carbon is usable, the organic halogen compounds in the exhaust gases can be decomposed, and SOx, NOx, HCl and heavy metals can be removed through adsorption.
