چکیده:

BiOCl microflowers were synthesized using bismuth nitrate pentahydrate and sodium chloride by microwave (MW) assisted synthesis method for 23 minutes at 180 W. Scanning electron microscopy (SEM) studies revealed a unique morphology of flower-like assemblies comprised of nanosheets. The X-ray diffraction (XRD) pattern showed that a highly pure and crystalline phase has been obtained. The energy dispersive X-ray (EDS) and photoluminescence (PL) and Fourier transform infrared (FTIR) spectroscopies were also used to evaluate the composition and structure of the product. The UV-vis diffuse reflectance spectroscopy (DRS) studies revealed the indirect band gap value of about 3.33 eV for the fabricated semiconductor.Photocatalytic studies confirmed that the BiOCl nanostructure could remove Rhodamine B (RhB) and Natural Red 4 (N-Red) dyes from the aqueous solutions by dye-photosensitized degradation mechanism under visible light illumination.
