Synthesis and analysis of bismuth oxychloride and bismuth tungstate using cyclic microwave irradiation method for photocatalytic applications

The BiOCl and Bi2WO6 successfully used the cyclic microwave method at 450 W. The structure, morphology, and optical properties were analyzed using X-ray diffraction (XRD), electron microscopy (SEM), transmission electron microscopy (TEM), and UV-visible spectrophotometer. The impact of dye treatment from photocatalytic synthesis, with and without pH adjustment, was also examined. It was discovered that the pH adjustment of the Bi2WO6 photocatalyst improved the treatment of MO dyes to 91% removal after 80 minutes. Additionally, the ability of the photocatalyst to treat other dyes, such as rhodamine B (RhB) and methylene Blue (MB), was evaluated.
