摘要：

Lamellar shaped BiOBr nanostructures were synthesized via electrospinning followed by calcination at 500 degrees C in air. These nano lamellae were comprised of micro/nano petals confirmed by electron microscopy. Lamellae crystal structures were identified as tetragonal by X-ray diffraction (XRD). X-ray photoelectron spectroscopy (XPS) was performed to identify the molecular composition, chemical interactions. These structures were utilized in photodegradation of Alizarin Red S (ARS) dye with respect to time. The half-life time of the dye was estimated about similar to 33.5 min under white light illumination. A plausible electron transfer mechanism was proposed with respect to standard hydrogen electrode (SHE) potential. (C) 2016 Elsevier B.V. All rights reserved.
