WebbAg 2 S–ZnO is found to be more efficient than commercial ZnO, prepared ZnO and TiO 2 –P25 at pH 9 for the mineralization of Acid Black 1. The effects of operational parameters such as the amount of photocatalyst, dye concentration, initial pH on photo mineralization have been analyzed. Mechanism of degradation by Ag 2 S–ZnO is proposed.
