Synthesis, Characterization and Photocatalytic Activity of Cobalt Doped TiO2 Nanophotocatalysts for Rose Bengal Dye Degradation under Day Light Illumination
Cobalt doped TiO2 nano photocatalysts were synthesized by sol-gel technique and is characterized by SEM, EDX and XRD. The Co-TiO2 catalyst is evaluated for its photocatalytic activity towards the degradation of Rose bengal under visible light radiations. Then the results were compared with the synthesized nano-TiO2. The effect of catalyst loading, initial dye concentration, pH, dissolved O2 on the photocatalytic activity is studied and the degradation kinetics is also studied. The photodegradation rates of Rose bengal reached 97.50% under visible light irradiation for 150 min.
