Using of TiO2-Coated Mesoporous Particles for Organic Dye Removal

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 TiO2 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 TiO2 particle reached only 40% of organic dye removal in 6 hours of irradiation time. On the other hand, the TiO2-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 TiO2-coated particles was higher than pure TiO2 particles. This outcomes suggested that the adding of produced mesoporous particles increased the efficiency of MB adsorption, leading to the improvement of photocatalytic activity.

Index Terms—Mesoporous particle, vetiver grass, titanium dioxide, organic dye.
