    • Abstract

       

      Nonionic polyacrylamide (NPAM) bismuth bromoxide (BiOBr) ultrathin hierarchical clusters have been prepared by a rapid solvothermal synthesis route. The formation mechanism of the NPAM-BiOBr ultrathin hierarchical clusterswas based on the strong bridging role of NPAM between the bismuthyl nitrate (BiONO$_3$) particles and subsequently results in tight junctions between BiOBr nanosheets. The structure, morphology and optical properties of the prepared samples were characterized by X-ray diffraction, Raman spectra, scanning electron microscopy, diffuse reflectance spectroscopy and photoluminescence. The photocatalytic performance of NPAM-BiOBr was evaluated by the degradation of Rhodamine B (RhB) and ciprofloxacin. The photocatalytic efficiency increased by 2.1 and 2.5 times of NPAM-BiOBr for RhB andciprofloxacin decomposition, respectively. The enhanced photocatalytic activity of NPAM-BiOBr was attributed to the increased light absorption capacity and lower recombination rate of the photo-generated electron and hole pairs.
