Cobalt(II) 2,9,16,23‐tetrasulphophthalocyanine and cobalt(II) 2,9,16,23‐tetra(chlorosulphonyl)phthalocyanine were supported on TiO 2 by reaction of the phthalocyanines with Ti(OR) 4 followed by sol‐gel synthesis. The thus obtained solid materials are stable in sulfide‐containing media and are therefore suitable as catalysts for HS oxidation. The structure of the samples was characterized by electron microscopy diffraction. The morphology of the matrix strongly depends on the cobalt phthalocyanine derivative. The pathalocyanines in the titania matrices are monomeric or dimeric depending both on the type of substituents of the CoPc derivative and on the titanium alkoxide used as precursors.
