The aim of this work was to synthesize semiconducting oxide nanoparticles using a simple method with low production cost to be applied in natural sunlight for photocatalytic degradation of pollutants in waste water. Iron titanate (Fe 2 TiO 5 ) nanoparticles with an orthorhombic structure were successfully synthesized using a modified sol–gel method and calcination at 750°C. The as-prepared Fe 2 TiO 5 nanoparticles exhibited a moderate specific surface area. The mesoporous Fe 2 TiO 5 nanoparticles possessed strong absorption in the visible-light region and the band gap was estimated to be around 2.16 eV. The photocatalytic activity was evaluated by the degradation of methylene blue under natural sunlight. The effect of parameters such as the amount of catalyst, initial concentration of the dye and pH of the dye solution on the removal efficiency of methylene blue was investigated. Fe 2 TiO 5 showed high degradation efficiency in a strong alkaline medium that can be the result of the facilitated formation of OH radicals due to an increased concentration of hydroxyl ions.

A solution-type TiO2-based photocatalyst for the decomposition of volatile organic compounds was synthesized using a modified sol-gel method under either alcohol (ethanol or isopropanol) or aqueous conditions. Anatase-type TiO2 was successfully synthesized with additional hydrothermal treatment using either type of medium. However, the aqueous condition for TiO2 synthesis was more convenient for the formation of anatase-type TiO2. Based on X-ray diffraction analysis data, the optimal hydrothermal treatment temperature was 80 °C for anatase-type TiO2 formation; at temperatures below 80 °C or above 90 °C, mostly rutile-type TiO2 was formed. The synthesized anatase-type TiO2 solution was applied to the surface of carbonized medium-density fiberboard (c-MDF). The anatase-type TiO2 on c-MDF showed good maintenance of toluene decomposition performance even after repeated use for 14 weeks.
