TiO2-xNy/Ag-PbMoO4 composite were synthesized by sonochemical method. The results revealed that the band-gap energy absorption edge of TiO2-xNy/Ag-PbMoO4 composite was shifted to a longer wavelength as compared to TiO2, TiO2-xNy, PbMoO4, and Ag-PbMoO4. The TiO2-xNy/Ag-PbMoO4 composite showed the enhanced photocatalytic activity for degradation of indigo carmine dye (ICD) under simulated solar light irradiation. The TiO2-xNy/Ag-PbMoO4 composite exhibited the highest percentage (95.4%) of degradation of ICD and the highest reaction rate constant (0.0244 min-1) in 2 h. The results suggested that a good combination of Ag and TiO2-xNy nanoparticles has great influence on the photocatalytic behavior of PbMoO4.
