- Abstract
The development of new efficient photocatalysts is critical for a variety of applications including water purification and water splitting. Unfortunately, because TiO2 has a wide band gap, the photocatalytic applications of TiO2 NTAs are restricted to light in the ultraviolet (UV) range. Nanosized barium carbonate nanoparticles were prepared by a precipitation method at relatively low temperatures. The prepared samples were characterized by X-ray diffraction, UV-Visible diffuse reflectance spectroscopy, Fourier-transform infrared spectroscopy and scanning electron microscopy with energy-dispersive X-ray spectroscopy techniques. The nanocomposite exhibited a strong photocatalytic activity for decomposition of Crystal violet (CV) under visible light irradiation. The influences of catalyst amount, initial Crystal violet concentrations, pH of the reaction solution and different anions on CV decolorization and degradation reaction kinetics were investigated. The dye could be decolorized more efficiently in acidic media than alkaline media. Furthermore, the photocatalyst indicated phenomenal strength after four response cycles. At last, the conceivable component for the action upgrade was examined in detail.
