Abstract
Precursor CaCu3Ti4O12 has been obtained using solution method in acetic acid medium, it was annealed at 100, 200, 400, 600 800, and 1100°C. Sintered powders have been studied by physicochemical methods of analysis. According to X-ray powder diffraction, completely formed crystal structure CaCu3Ti4O12 exists at 1100°C, the particle size of the prepared powder is 1–10 µm. Thermal analysis with allowance for mass spectrometric analysis system of vapor phase has revealed process mechanisms. Effect of dried at 100°C powder of precursor and CaCu3Ti4O12 on the photocatalytic activity of Rhodamine B decoloration has been shown. Pseudo-first and pseudo-second order kinetics for Rhodamine B adsorption on samples annealed at 100 and 1100°C has been revealed.
