Synthesis of cobalt (II) phthalocyanine complex with axial isonicotinic acid ligand: Molecular engineering of a photocatalyst for the degradation of benzene as a representative volatile organic compound
Axial modification for cobalt (II) phthalocyanine (CoPc) was done to enhance the catalytic activity of TiO2 by photodegrading benzene using indoor fluorescent lighting. The isonicotinic acid (IsA) ligand attached to the axial position of CoPc produced covalent anchor to TiO2 basing from the nanostru...

Axial modification for cobalt (II) phthalocyanine (CoPc) was done to enhance the catalytic activity of TiO2 by photodegrading benzene using indoor fluorescent lighting. The isonicotinic acid (IsA) ligand attached to the axial position of CoPc produced covalent anchor to TiO2 basing from the nanostructures synthesized using horizontal vapour phase crystal growth technique. Electrospray ionization mass spectrometry, differential thermal analysis, and geometry optimization calculations proves the existence of IsA occupying two axial positions in CoPc. Photodegradation analysis showed improvement of CoPc(IsA)-TiO2 on degradation of benzene by increasing the rate constant, as compared to plain TiO2 and CoPc-TiO2. GC-MS analysis showed oxidation products of benzene adsorbed on TiO2 surface which are hydrocarbon clusters synthesized from series of free radical reactions. The study provides usage of axial modification for facile synthesis of sensitizers for TiO2 for use in photocatalytic degradation of indoor air pollutants, specifically volatile organic compounds. |
