The nanophotocatalytic process using semiconducting oxides with a nanostrucrure is one of the technologies used for the destructive oxidation of organic compound such as dyes. In this paper, photocatalytic degradation of erythrosine using N, S-codoped TiO2 as semiconductor prepared by sol-gel method is reported. The rate of photocatalytic degradation of dye was monitored spectrophotometrically. The effect of variation of different parameters like pH, concentration of erythrosine, amount of photocatalyst, dopant percentage and light intensity on the rate of photocatalytic degradation of dye was also observed. A tentative mechanism for photocatalytic degradation of the dye has also been proposed
