Enhanced Photocatalytic Degradation of Methyl Orange under UV Irradiation Using Noble Metal-Loaded WO3/WS2

This study developed WO 3 /WS 2 composites loaded with noble metals to degrade methyl orange under UV light. Pure WO 3 /WS 2 and variations loaded with Au, Ag, Pt, Ru, and Rh were among the photocatalysts. To examine the materials' structural, morphological, and optical characteristics, X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-visible spectroscopy were used. The highest photocatalytic activity was observed with Au@WO 3 /WS 2 , degrading MO by 98.59 %. The synergistic interactions between Au nanoparticles and the WO 3 /WS 2 heterostructure improved charge separation and light absorption, indicating the composites' potential for effective UV-active photocatalysts for environmental remediation.
