Efficient Sunlight Active Nanocomposite Photocatalyst for Degradation of Pollutant Organic Dyes

Abstract:

The sunlight activated photocatalysts are urgently needed for the applications of photocatalytic techniques to environmental pollutants removal. Herein, we report the one-step hydrothermally prepared CdS/TiO₂ nanocomposite photocatalyst that is active in the degradation of pollutant organic dyes under solar light. The morphology and components are confirmed by TEM, SEM and XRD. With methylene blue (MB) as the model pollutant organic dye, the photocatalytic activity of CdS/TiO₂ nanocomposite photocatalyst under sunlight is demonstrated, and 80% MB is removed after 120 minutes sunlight illumination. Besides, the influences of pH, the amount of photocatalyst and the addition of H₂O₂ on photocatalytic activity for the degradation of MB are also investigated to mimic water treatment process.
