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...
