In present work efficiency of CeFeO3 as photocatalyst for degradation of Acid Black 194 was studied. Photocatalytic bleaching of Acid Black 194 was observed spectrophotometrically. The influence of variation of different reaction parameters such as concentration of dye; pH and amount of photo catalyst were observed. The optimum conditions for photocatalytic degradation have been established. The optimum conditions for the degradation of Acid Black 194 dye have been found as dye concentration 3x10-5M, pH 8.0 and 0.06 g /100 ml catalyst dose. The kinetics of degradation of the dye follows first order kinetics. A tentative mechanism for degradation of dye by CeFeO3 has been proposed. The presence of hydroxyl radical as an active oxidising species has been confirmed.
