Nanosheets of BiOCl Incorporated in Microflowers: Microwave Assisted Synthesis and Dye-Photosensitized Removal of Pollutants

Nanosheets of BiOCl Incorporated in Microflowers: Microwave Assisted Synthesis and Dye-Photosensitized Removal of Pollutants

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 diffrac...
