Synthesis of Acid Co-Precipitated WO3 Nanoflowers and Its Characterization: Structural, Optical, and Morphological Insights

In the current research, we delve into the synthesis and comprehensive characterization of tungsten oxide (WO₃) nanostructures, unveiling novel insights that promise advancements in various technological realms through a facile acid co-precipitation method. The obtained material underwent characterization employing a variety of analytical methods, including X-ray diffraction, UV-Vis spectroscopy, and scanning electron microscopy. X-ray diffraction was employed to elucidate the crystallographic details, identify different phases, and estimate crystallite size and microstrain values using the Williamson-Hall plot and Debye-Scherer method. A band gap of approximate 2.5 eV was determined through the analysis of UV-Vis spectroscopy, along with the assessment of additional optical properties such as absorbance range, refractive index, and HOMO-LUMO levels. The morphological investigation using FESEM images revealed the formation of nanosheets arranged in a flower-like structure. Therefore, our investigation demonstrated that the as- synthesized tungsten oxide (WO3) exhibits promising properties, showcasing excellent outcomes in optical, structural, and morphological analyses. Notably, the results indicate highly favourable characteristics for various applications, paving the way for their utilization in efficient and sustainable energy conversion systems.
