Sol-gel method was used to synthesize undoped and zinc doped TiO{sub 2} with varied dopant concentrations using titanium tetraisopropoxide and zinc acetate as precursors. The synthesized catalyst samples were characterized by various techniques such as X-ray powder diffraction (XRD), UV-vis diffuse reflectance (DRS). The photocatalytic activity was determined by means of degradation of azo dye Eriochrome Black T. The results revealed that Zn doped TiO{sub 2} nanoparticles exhibited better results as compared to undoped TiO{sub 2} nanoparticles. Zn doped TiO{sub 2} (0.7mol %) nanoparticles exhibited the highest photocatalytic activity.
