Polycrystalline titanium dioxide (TiO2) thin films were prepared using spray pyrolysis at various temperatures and showed excellent photoelectrocatalytic performance in the oxidative degradation of model pollutants.
This work reports the preparation of polycrystalline titanium dioxide (TiO2) thin films using spray pyrolysis technique at various temperatures to access their photoelectrocatalytic (PEC) performance. The films were characterized by photocurrent response measurements, X-ray diffraction, Scanning electron microscopy, Elemental analysis, Fourier-transform Raman spectroscopy and UV-vis spectroscopy. The TiO2 showed heterogeneous photocatalytic potential against the oxidative degradation of Phthalic acid (PA) and Benzoic acid (BA) which were used as model pollutants. The PEC behavior of the typical TiO2 film was excellent for oxidative degradation of both pollutants under UV irradiation.
