The photocatalytic activity of CoPc isa 2 -TiO2 compared to TiO2 December 20 2015 showed an increase in the extent of degradation. The axial isonicotinic acid ligand attached to Accepted 7 April 2016 CoPc improved the degradation rate of benzene as compared with unligated CoPc-TiO2 which Available online may be attributed to the enhancement of electronic structure in the complex due to the 7 April 2016 additional isonicotinic acid ligand and its possible attachment to the TiO2 surface through the Keywords carboxylic acid moiety. Therefore covalently-linked CoPc isa 2 to TiO2 can enhance the extent Axially-ligated cobalt II phthalocyanine of photodegradation of benzene and other common volatile organic compounds under indoor Photocatalyst
