The development of semiconductor photocatalysis for a wide range of environmental and energy applications. One of the most significant and commercial advances has been the development of visible light active TiO2 photocatalytic materials. In the present study, a visible light active TiO2 photocatalyst was prepared through Nitrogen doping by using Ammonia as Nitrogen source. Preparation was performed by a sol-gel method at various temperatures such as 400 oC, 600 oC and 800 oC. The resulting photocatalyst was characterized by XRD, SEM, EDAX. The decrease in concentration of rhodamine B was monitored by UV-Visible spectroscopy. The characterizations found that the photocatalyst possessed a high surface area and a crystalline size is about-19 nm, 28 nm and 52 nm respectively. On the degradation of rhodamine B in water under visible light irradiation [λ= 554 nm]. The photocatalytic activity increased with decrease in concentration of catalyst and increase in light intensity.
