Efficient photocatalytic degradation of Rhodamine B by a novel CeO<inf>2</inf>/Bi<inf>2</inf>WO<inf>6</inf>composite film
© 2016 Elsevier B.V. The CeO2, Bi2WO6and 0.4CeO2/0.6Bi2WO6photocatalyst films were fabricated by a doctor blading method. The film thickness of the as-prepared samples was varied to one, two and three layers. The physicochemical properties of all sample films were characterization by X-ray diffracti...

The CeO2, Bi2WO6and 0.4CeO2/0.6Bi2WO6photocatalyst films were fabricated by a doctor blading method. The film thickness of the as-prepared samples was varied to one, two and three layers.

Photocatalytic activities of CeO2, Bi2WO6and 0.4CeO2/0.6Bi2WO6films were investigated via the degradation of Rhodamine B (RhB) under visible light irradiation.
