Description 590-599
Bi2WO6 photocatalysts were synthesized via hydrothermal process and solid-state reaction techniques. The results
revealed that Bi2WO6 prepared via hydrothermal route were composed of numerous square nanoplates, and Bi2WO6
prepared via solid-state route were just irregular broken pieces of the material. The photocatalytic activity of both the
Bi2WO6 samples prepared via two different techniques under Xe lamp of 300W was evaluated for degradation Rhodamine B
(RHB) and Methylene blue (MB). The hydrothermally prepared Bi2WO6 nanoplates exhibited better photocatalytic activity.
Nearly 56% of RHB and 53% of MB were degraded within 40mins respectively, which was three times better than the
Bi2WO6 synthesized by solid-state reaction. The better photocatalytic performance can be credited to the geometry, porosity,
and the higher surface area of the hydrothermally prepared Bi2WO6 photocatalyst.
