Peculiarities of Synthesis of Nanodisperse Barium Titanate and Investigation of its Properties
Abstract
The interaction between barium oxide and titanium dioxide with different specific surface and crystalline structure by mechanochemichal, microwave and hydrothermal treatments have been investigated. It has been found by means of XRD, FTIR, ESR and UV-VIS spectroscopy that the use of low-temperature modification of TiO2 leads to the formation of barium titanate nanoparticles with high specific surface and defect structure. A definite increase was observed in absorption as well as shift of the absorption edge in the visible region, higher activity in the reaction of photocatalytic destruction of Safranin T in aqueous solutions for the synthesized samples of barium titanate. An enrichment of the surface by Bronsted basic centers occurs at when barium titanate is synthesized in an aqueous medium.References
