Summary: | In this article, modified TiO2 and Mg-TiO2 nanoparticles was prepared by the facile sonochemical method. The crystal structure evolution and elemental composition were analyzed by X-ray crystallography and X-ray photoelectron spectroscopy. The calculated band gap energy of Mg-TiO2 nanoparticles was lower than that of pure TiO2-P25. The Fourier Transform Infrared (FT-IR) spectral study established the substitution of Mg2+ on the TiO2 surface. The Raman spectroscopy confirms that the Mg2+ ions were in situ doped on the surface of TiO2 nanoparticles. The photocatalytic efficiency of the synthesized Mg-TiO2-P25 nanoparticles was investigated by performing photocatalytic degradation of persistent Congo red dye under visible light irradiation. It has been found that the Mg-TiO2-P25 nanoparticles possess better catalytic activity than pure TiO2-P25 and modified 1102 nanoparticles. |
