ABSTRACT
The paper presents some application of barium titanate synthesized by different methods. Barium titanate samples were prepared by four procedures: solid state, mechanochemical as direct synthesis and modification as well as hydrothermal and microwave. The obtained samples were systematically studied using X-ray diffraction, nitrogen adsorption, Fourier transform infrared spectroscopy (FTIR), potentiometric titration, and quasi-elastic light scattering and zeta potential measurements. The values of pHpzc (point of zero charge) and pHIEP (isoelectric point) characteristic of the electrical double layer were determined. The prepared samples were tested as photocatalysts under visible light. As a result, relationship between the conditions of barium titanate synthesis, its physicochemical and electrokinetic parameters, as well as photocatalytic activity under visible light was first established.
