Anatase-3DOM Structure for Reactive Red Dye Photocatalytic Degradation

Main Article Content

Tanya Kiatboonyarit


Photocatalysts TiO2-powder and TiO­2-3DOM (Three-dimensionally ordered macroporous, 3DOM) were prepared by the sol-gel method and calcined at 723 K. The TiO2 and Ce/TiO2 photocatalysts showed only anatase phase without CeO2 and the particle size of the Ce/TiO2-3DOM was smaller than the TiO­2-powder. The Poly(methyl methacrylate, PMMA) was the template for TiO2 particle-orientation as investigated by SEM. The stoichiometry of element and the molar percentage of Ce/Ti in the sample were determined by EDS. The photocatalytic degradation of reactive red dye was evaluated by UV-Vis spectroscopy. TiO2-powder-723 showed the highest photocatalytic activity compared to others due to their morphology and particle size.
