Photocatalytic degradation of organic dye using FexOy -TiO2 and powered by solar cells

The main objective of this work is to evaluate the performance of novel semiconductor FexOy-TiO2 under visible lamp and the use of the photovoltaic panel as a direct energy source. The results showed that 91.81% occurred by using lamp of 20 W under the condition of [FexOy-TiO2] = 0.5g/L, [BBF] = 20 mg/L, [H2SO4] = 0.1 M, pH = 3.8, P = 18 W and three hours of reaction. It was also found that the presence of PO43- and S2O82- (3 g/L) increase the rate of degradation to 97.72% in about 1.5 h. The second part of this work was dedicated to choose a lamp with the best intensity of irradiation. The maximum of current intensity generated by solar cells reaching the values of 3,400 mA at 11.08 h and 2,260 mA at 13.83 h by using lamps of 20 W and 75 W respectively.
