Year: 2025
Type: conference-paper
Abstract: This manuscript explores the synthesis and characterization of tungsten trioxide (WO3) nanoparticles and their nanocomposites with reduced graphene oxide (rGO) via an in situ hydrothermal method. Through systematic investigation of WO3-rGO nanocomposites with varying weight ratios, denoted as WO3-rGO3%, WO3-rGO7%, and WO3-rGO15. X-ray diffraction and Raman spectroscopy confirm the crystallinity of WO3 and the successful integration of rGO. Transmission electron microscopy reveals well-dispersed WO3 nanoparticles on rGO sheets, and diffuse reflectance spectroscopy indicates a slight reduction in the band gap energy for WO3-rGO nanocomposites. Fluorescence emission spectra exhibit significant quenching, suggesting enhanced interfacial contact between WO3 particles and rGO nanosheets. These findings underscore the potential of WO3-rGO nanocomposites for diverse applications, positioning them as promising candidates in the burgeoning field of advanced composite nanomaterials.
