Abstract : In this study, phenylene diamine (an organic pollutant) was photo catalytically degraded by using TiO2-rGO nanoparticles in the UV radiation. Graphite powder was used to produce the rGO using modified hummers' method. Titanium isopropoxide was used to prepare TiO2 using hydrolysis. Hydrothermal method was used to produce TiO2-rGO nanoparticles. XRD and SEM were done to characterize the catalyst. The experiments under UV-light were conducted in the photo reactor to determine the percentage of degradation. The change in concentration vs time was observed with the change in absorbance value in the UV spectroscopy. The effect of catalyst concentration, phenylene diamine concentration and pH was also studied. Kinetics study was carried out and the degradation mechanism of phenylene diamine was discussed.
