Photodegradation of Rhodamine B and Bisphenol A Over Visible-Light Driven Bi7O9I3-and Bi12O17Cl2-Photocatalysts Under White LED Irradiation

Two different bismuth oxyhalides photocatalysts Bi7O9I3 and Bi12O17Cl2 were obtained by oil bath and hydrothermal methods. The micro/nano-structures obtained were characterized by XRD, SEM, DRS and XPS. The XRD patterns are identical to those already reported. SEM revealed the formation of hierarchi...
