Hydrothermal preparation of visible-light-driven Br-doped Bi2WO6 photocatalyst

Bi2WO6 loaded with 0-3 wt% Br was hydrothermally prepared and further characterized by XRD, Raman spectroscopy, TEM, SAED and XPS. In this research, both doped and un-doped samples were uniform orthorhombic Bi2WO6 nanoplates. Their photocatalysis was evaluated through photodegradation of rhodamine B under visible radiation. Bi2WO6 loaded with 3 wt% Br has the highest activity and can be used as a visible-light-driven photocatalyst. (C) 2017 Elsevier B.V. All rights reserved.
