The photo catalytic removal by using semiconductors especially TiO2 and SiO2 composite (TSC) were used out in presence of light to observe good semiconducting property. Preparation, characterization and applications of semiconducting materials were studied. The purification of the Wastewater in presence of photo catalysts were carried out. The photocatalysts remove of dyes, heavy metals and hardazous organic compound. The time required for photo catalytic 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. Results of the study showed that dyes removal in the dark was very low for the three types of Nano materials under the study conditions used. However, appreciable removal of dyes and metals was observed when using TSC for UV lights, the degradation of the dye by using semiconducting materials were characterized by XRD, and SEM analysis before and after application of photo catalysts.
