Synthesis of polymeric and low molecular weight phthalocyanines from nitriles and metal carbonyls on SiO2 and TiO2 and catalytic activities in the sulfide oxidation

A new method for coatings of polymeric phthalocyanines and for comparison a lso of low molecular weight phthalocyanine metal complexes (W, Cr, Mo, Co) on quartz and titanium dioxide was developed by the reaction of metal carbo nyls adsorbed on the carriers with tetracarbonitriles or phthalonitrile. By UV-vis or IR spectra the formation of structural uniform polymeric phthalo cyanines on the carriers is established. The compounds are used then to com pare their catalytic and photocatalytic activities in the oxidation of sulf ide as test reaction. Copyright (C) 2001 John Wiley & Sons, Ltd.
