Oxidative degradation of phthalic acid using TiO2 photocatalyst

TiO2 is one of the well-known multipurpose material for different applications such as gas sensors, catalysis, solar cells, optoelectronic devices, etc. TiO2 is widely used as photocatalyst due to interest optical and electrical properties. In the present work, TiO2 photocatalyst is used to study the degradation of phthalic acid under ultraviolet light illumination. The prepared TiO2 photocatalyst is characterized by different characterization techniques such as X-ray diffraction, Raman spectroscopy, scanning electron microscopy. The end result shows that the degradation percentage of phthalic acid using TiO2 photocatalyst has reached 41.93% after 320 min. under ultraviolet light illumination. The amount of mineralization of phthalic acid is confirmed by chemical oxygen demand measurements.
