Photodegradation of Malachite Green by Nanostructured Bi 2 WO 6 Visible Light-Induced Photocatalyst

Figure 7

The photocatalytic degradation of malachite green time under optimal conditions (the initial concentration of malachite green, initial pH value, and the concentration of photocatalyst are 10 mg·L−1, 2, and 1.0 g·L−1, resp.): (a) Bi2WO6 under Xe lamp (as indicated by black square; (b) reference P25 under Xe lamp (as indicated by white triangle, simulated sunlight); (c) reference P25 under visible light (as indicated by black triangle); (d) Bi2WO6 under visible light and anoxic condition.
