摘　　要：This work presents result on yttrium-doped titanium dioxide(YTO) thin films using a cost-effective spray pyrolysis technique for the photoelectrocatalytic degradation of phthalic acid(PA) and benzoic acid(BA).The physicochemical properties of YTO thin films were studied using X-ray diffraction,Raman spectroscopy,X-ray photoelectron spectroscopy,field-emission scanning electron microscopy,UV-vis spectroscopy,etc.The obtained results confirm the presence of yttrium in the host lattice.The band bending and flat band positions were studied using Mott-Schottky analysis.The film with 1% doping amount shows the highest degradation efficiency for both the model pollutants compared to TiO_(2).The stability of 1% YTO film confirms excellent performance analyzed by recycling tests using a UV-vis spectrophotometer.These results highlight the significance of rare earth metal doping in TiO_(2)for improved photoelectrocatalytic degradation efficiency.
