Abstract
The photocatalytic degradation on semiconductors especially on TiO2 and ZnO were carried out in presence of light to observe good semiconducting property. In this paper the preparation, charectrization and applications of semiconducting materials were studied. The purification of wastewater in the presence of photocatalysts were carried out. The photocatalytic degradation of dyes Methylene blue, Acid blue-29, and Alizarin red-S were used in this experiment. A Total time required for photocatalytic degradation is different for different effluent samples, varied from 60 to 180 min. Parameters like band gap; Dose of Catalysts concentrations of effluent, pH, etc were studied. Studies The TiO2 shows more photocatalytic efficiency than ZnO. The degradation of the dye by using semiconducting materials were characterized by XRD, SEM and EDX analysis before and after application of photocatalysts.
