Sonochemical synthesis of TiO2-xNy-coupled Ag-PbMoO4 nanocomposites with enhanced photocatalytic activity under simulated solar light |
| 초록 |
The TiO2-xNy-coupled Ag-PbMoO4 nanocomposites have been synthesized by sonochemical synthesis. The as-prepared samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), diffuse reflectance UV-vis spectroscopy (UV-vis-DRS), X-ray photoelectron spectroscopy (XPS). The results revealed that the band gap energy absorption edge of TiO2-xNy-coupled Ag-PbMoO4 nanocomposites shifted to longer wavelength as compared to TiO2-xNy and Ag-PbMoO4. According to FE-SEM studies, Ag-PbMoO4 gets to be decorated with evenly distributed TiO2-xNy nanoparticles. The photocatalytic activity of TiO2-xNy-coupled Ag-PbMoO4 nanocomposites for the inactivation of green tide (Tetraselmis suecica) and the degradation of indigo carmine (IC) dyes under simulated solar light was enhanced as compared with TiO2-xNy and Ag-PbMoO4. The TiO2-xNy-coupled Ag-PbMoO4 nanocomposites may facilitate the charge transfer process more efficiently by inhibiting electron-hole recombination, which enhanced the photocatalytic activity. |
