Summary:•Hierarchical flower-like Bi2WO6 as a semiconductor.•It enables us to synthesize by hydrothermal route.•A promising material for photocatalysis.•In this research, 3% Ag doped Bi2WO6 shows the highest photocatalytic activity. In this research, 0–3mol% Ag doped Bi2WO6 hierarchical multilayered flower-like assemblies were successfully synthesized by a simple hydrothermal method at 180°C for 24h. 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 (λ>420nm). The 3mol% Ag doped Bi2WO6 showed the highest photocatalytic activities of 98.20% within 180min.
