Synthesis of V₂O₅ nanowires decorated with BiVO₄ nanoparticles via a simple spin-coating method

This study has explored the development of V₂O₅/BiVO₄ nanowire thin films using a spin-coating method prepared using two distinct approaches: solution and powder processes. We have investigated the impact of these preparation methods on the physicochemical properties of V₂O₅/BiVO₄ nanowire films. Various characterization techniques such as X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and optical spectroscopy have been employed to examine the crystal structure, surface morphology, and light absorption behavior of the films. V₂O₅/BiVO₄ nanowire thin films were synthesized from a powder process, whereas conventional BiVO₄ films were synthesized from a solution. The findings from this comparative analysis provide valuable insights into the influence of the precursor preparation methods on the physicochemical properties of V₂O₅/BiVO₄ thin films.
