Specific features of the photocatalytic destruction of Safranin T on mechanochemically produced barium titanate
Possibility of producing powdered barium titanate with increased specific surface area and defective structure by mechanochemical treatment of barium titanyl oxalate and a mixture of barium and titanium oxides was studied. Samples were examined by means of X-ray phase and differential-thermal analyses, low-temperature nitrogen adsorption, EPR, and electronic absorption spectroscopy. The photoactivity of the mechanochemically activated powders in the reaction of Safranine T disintegration in aqueous solutions was analyzed.
