Synthesis and characterisation of WO₃ and Ag₂O nanoparticles and their nanocomposite for photocatalytic degradation of dyes

In this research, tungsten oxide (WO3), silver (Ag2O), and Ag2O/WO3 nanocomposites were synthesised by precipitation sonication method, respectively. X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM) UV-Visible used to confirm the structural, spectral, morphological, optical properties of as-synthesised samples, The as-prepared nanocomposite showed improved photocatalytic degradation activity for rhodamine B methylene blue under solar light compared pristine WO3 Ag2O. percentage values 79.6%, 86.1% 90.8% WO3, Ag2O 70.9%, 80.7% 87.25% B. One possible reasons behind was decreased recombination photo-generated holes electrons due formation between Optical band gap 2.93 eV, 1.59 eV 1.38 Mott-Schottky plot confirmed p-type n-type behaviour
