Solar assisted photo-catalytic degradation of Amido Black 10B over cobalt, nickel and zinc metalloporphyrins

Abstract

The tetraphenyl porphyrins (TPP) and metalloporphyrins such as CoTPP, NiTPP and ZnTPP were synthesized, purified and characterized by UV-Visible spectroscopy, IR spectroscopy, (1)H NMR spectroscopy and elemental analysis.The results have been discussed in the light of magnetic susceptibility; diffuse reflectance spectroscopy (DRS), electron spin resonance (ESR), X-ray diffraction data and solar assisted photodegradation.The semi conducting properties of these porphyrins were employed for trapping the solar radiations for the photodegradation of azo dye such as Amido Black 10B at different pH conditions.This reaction was studied as a model reaction for finding the photoactivity of these compounds.
