Synthesis and characterization of hierarchical multilayered flower-like assemblies of Ag doped Bi2WO6 and their photocatalytic activities

In this research, 0-3 mol% Ag doped Bi2WO6 hierarchical multilayered flower-like assemblies were successfully synthesized by a simple hydrothermal method at 180 degrees C for 24 h. The XRD, FE-SEM, FTIR and Raman analyses revealed the presence of flower-like Russellite Bi2WO6 structures which were constructed from a large number of orderly arranged 2D layers of interconnected nanoplates. Their photocatalytic activities were evaluated by photodegradation of rhodamine B (RhB) under Xe visible light irradiation (lambda > 420 nm). The 3 mol% Ag doped Bi2WO6 showed the highest photocatalytic activities of 98.20% within 180 min. (C) 2013 Elsevier Ltd. All rights reserved.
