Nano-size TiO 2 particles were obtained using various mesoporous materials and the particle sizes were determined by the pore sizes of mesoporous materials. The bandgap increments due to quantum size effect were observed in both anatase TiO 2 and rutile TiO 2 . The bandgap increment in anatase TiO 2 did not affect the efficiency of photocatalytic oxidation of 2-isopropyl-6-methyl-4-pyrimidinol. However, the bandgap increment in rutile TiO 2 enhanced the photocatalytic activity by virtue of the increase in redox potential of TiO 2 .
