Abstract
In the present work, mesoporous particles was produced by calcining vetiver leaves at 600°C. Then, it was coated by TiO2 using sol-gel method. The crystal structure of TiO<sub>2</sub> coated particle was investigated using X-Ray Diffraction (XRD) technique. The organic dye removal efficiency were examined using photodegradation of methylene blue (MB) under UV-A irradiation. The pure TiO<sub>2</sub> particle reached only 40% of organic dye removal in 6 hours of irradiation time. On the other hand, the TiO<sub>2</sub>-coated mesoporous particles got >90% of organic dye removal in 6 hour of irradiation time. It can be said that the organic dye removal efficiency of TiO<sub>2</sub>-coated particles was higher than pure TiO<sub>2</sub> particles. This outcomes suggested that the adding of produced mesoporous particles increased the efficiency of MB adsorption, leading to the improvement of photocatalytic activity.
