AB  - 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 (Fe2TiO5) nanoparticles with an orthorhombic structure were successfully synthesized using a modified sol-gel method and calcination at 750 degrees C. The as-prepared Fe2TiO5 nanoparticles exhibited a moderate specific surface area. The mesoporous Fe2TiO5 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. Fe2TiO5 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.

AB  - In this work, nine products were prepared by modifying the experimental conditions (6, 12 and 18 hat 110, 135 and 160 degrees C) of hydrothermal treatment of starting nanoanatase in significantly less concentrated alkaline medium than usual in order to obtain a pure titanate phase. The nanocrystalline samples were characterized by XRPD, FESEM, HRTEM/SAED, EDS, TG, FT-IR, UV-Vis and BET analyses. The results revealed that the structure, texture, morphology and band gap energy of samples strongly depend on conditions of hydrothermal treatment. The intensification of hydrothermal treatment significantly increases the solubility of TiO2 promoting the changes in morphology from nearly spherical titania nanoparticles to elongated titanate nanosheets. The single titanate phase was obtained after energetically the most intensive treatment, i.e. 18 hat 160 degrees C. The step-by-step optimization was thus necessary to finally distinguish the titanates from titania in terms of structural and spectral properties and to finally allow the clarification of long-standing confusion between titania and titanates. The obtained single titanate phase was furtherly used to fabricate a humidity sensor, which showed remarkably rapid response and quick recovery time.
