Nano-sized WO3 Structures via Novel Chemical Approach: Temperature Influence

March 18, 2021 Physical Science 0

Due to its promising and remarkable properties, tungsten trioxide (WO3) has gotten a lot of attention. The starting material for the preparation of WO3 nanostructures in this study was tungsten carbide (WC). To confirm the transformation of WC to WO3 and investigate the temperature effect on these nanostructures, the obtained samples were annealed at various temperatures and characterised using various techniques. After annealing at 500 and 600°C for 5 hours in an air atmosphere, the prepared WO3 nanostructures crystallised into a monoclinic phase, according to the X-ray diffraction (XRD) pattern. The temperature effect on the morphologies of nanostructures was highlighted by scanning electron microscopy (SEM) images. The nanostructures have a rod-like shape with uniform distribution after annealing at 500°C. However, the SEM picture taken at 600°C reveals an exceptional porous morphology with a hollow sphere-like shape. The structural composition and purity of the formed WO3 were verified using Fourier transform infrared (FTIR) spectroscopy. Our simple method proved to be a promising route for preparing WO3 nanostructures as high-performance materials for advanced applications, based on the experimental results.
