The present work incorporates the study of efficiency of carbon doped TiO2 for photocatalytic degradation of Evans blue dye. Effect of some factors such as catalyst dose, concentration of dye, intensity of light, pH etc., on degradation of the dye was examined. The reaction followed pseudo first order kinetics. Participation of •OH free radical was confirmed by scavenger studies. Optimum conditions were determined by variation of operational parameters. A tentative mechanism for photocatalytic degradation of Evans Blue has been proposed.
