Synthesis and Characterization of Titania Photocatalyst Nano-particles of Controlled size and Shapes for waste water treatment

Titania nanotube was synthesized through the hydrothermal route and used for the degradation of azo dye (Sulfan blue) by means of photocatalysis process. The particle sizes, surface morphology, crystal structure were characterized by field emission scanning electron microscopy (FESEM), transmission...
