Abstract
This study presents the preparation of tungsten trioxide (WO3) nanoparticles by acidic precipitation using sodium tungstate as a precursor. Composite synthesis was selected among various modification methods to investigate catalytic activity improvement. WO3:polyaniline (PANI) nanocomposites with different weight ratios were prepared. The synthesized nanocomposites were characterized by field emission scanning electron microscopy, X-ray diffraction, thermogravimetric analysis–differential thermal analysis, and Fourier transform infrared spectroscopy. Results revealed the successful preparation of WO3: PANI nanocomposites. These nanocomposites exhibit higher thermal stability compared with PANI, indicating a satisfactory interaction between WO3 and PANI. The synthesized nanocomposites are being evaluated for their catalytic activity.
