Synthesis of polymeric and low molecular weight phthalocyanines from nitriles and metal carbonyls on <font>SiO</font>₂ and <font>TiO</font>₂ and catalytic activities in the sulfide oxidation

Abstract

A new method for coatings of polymeric phthalocyanines and for comparison also of low molecular weight phthalocyanine metal complexes ( W , Cr , Mo , Co ) on quartz and titanium dioxide was developed by the reaction of metal carbonyls adsorbed on the carriers with tetracarbonitriles or phthalonitrile. By UV-vis or IR spectra the formation of structural uniform polymeric phthalocyanines on the carriers is established. The compounds are used then to compare their catalytic and photocatalytic activities in the oxidation of sulfide as test reaction.
