Abstract

The reactivity of phthalonitrile, tetrafluorophthalonitrile and 4,5-dibutoxyphthalonitrile with unmodified surfaces of ZnO and SiO 2 and with the modified systems SiO 2/ Cp 2 Co , ZnO / Cp 2 Co , SiO 2/ Zn ( AcAc )2 prepared by deposition of cobaltocene ( Cp 2 Co ) and zinc acetylacetonate Zn ( AcAc )2, was studied ("in-situ-synthesis") in processes of phthalocyanine coatings. The formation of structural uniform phthalocyanines on carriers were established by UV-vis and mass spectra. The compounds were used then to compare their catalytic and photocatalytic activities in the oxidation of sulfide as a test reaction.
