Phthalocyanine coatings on silica and zinc oxide: Synthesis and their activities in the oxidation of sulfide
Abstract
The reactivity of phthalonitrile, tetrafluorophthalonitrile and 4,5-dibutoxyphthalonitrile with unmodified surfaces of ZnO and SiO2 and with the modified systems SiO2/Cp2Co, ZnO/Cp2Co, SiO2/Zn(AcAc)2 prepared by deposition of cobaltocene (Cp2Co) 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.
