Hassan Alshamsi

This is expected under visible light irradiation. Enhancing of photocatalytic activity of TiO2/CNTs hybrid nanocatalyst is arises from the fact that CNTs can act as a photosensitising agent under visible light irradiation .On increasing CNTs weight ratio, more visible light is absorbed and hence more dye molecules are degraded.

Thanks a lot dear Hassan Alshamsi
