Abstract

The TiO_2-xN_y/Ag-PbMoO₄ nanocomposites were prepared by sonochemical method. The as-prepared powders were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and diffuse reflectance UV-vis spectroscopy (UV-vis-DRS). The results revealed that the band gap energy absorption edge of TiO_2-xN _y/Ag-PbMoO₄ nanocomposites red shifted as compared to TiO_2-xN_y and Ag-PbMoO₄. According to FE-SEM studies, Ag-PbMoO₄ gets to be decorated with evenly distributed TiO_2-xN_y nanoparticles. The photocatalytic activity of TiO_2-xN_y/Ag-PbMoO₄ nanocomposites for photoinactivation of green tide (Tetraselmis suecica) under simulated solar light was enhanced as compared with TiO_2-xN_y and Ag-PbMoO₄. The TiO_2-xN_y/Ag-PbMoO₄ nanocomposites showed the highest percentage (100%) of removing of Tetraselmis suecica after 25 min. The TiO_2-xN_y/Ag-PbMoO₄ nanocomposite may facilitate the charge transfer process more efficiently by inhibiting electron-hole recombination, which enhanced the photocatalytic activity.
