摘要

采用溶胶-凝胶法制备了钴掺杂TiO2纳米光催化剂,并用SEM、EDX和XRD对其进行了表征。研究了Co-TiO2催化剂在可见光下对孟加拉玫瑰降解的光催化活性。然后将所得结果与合成的纳米tio2进行比较。研究了催化剂负载、初始染料浓度、pH、溶解氧对光催化活性的影响及降解动力学。在可见光照射150 min下,孟加拉玫瑰的光降解率达到97.50%。

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.
