Electrochemical assisted photodegradation of oxalate ions using sol–gel coated TiO2 on ITO glass

Electrochemical assisted photodegradation of oxalate ions using titanium dioxide coated on indium tin oxide glass substrates were studied. The titanium dioxide (TiO2) films were prepared by dip-coating method. The photodegradation study under illumination with halogen and ultraviolet lamp was carried out using linear sweep voltammetry. The effect of heat treatment, light source, intensity of light, concentration of oxalate ion, number of dip-coating and applied potentials have been investigated. Ultraviolet light was found to induce higher photodegradation reaction compared to halogen lamp.
