N2 - Bi2WO6 photocatalyst film prepared by a facile chemical bath deposition (CBD) method was modified by polyaniline (PANI) through in situ polymerization of vapor phase aniline. The photocatalytic activities of the PANI/Bi2WO6 film were evaluated by the degradation of a widely used dye, tetraethylated rhodamine (RhB), and a general gaseous indoor air pollutant, acetaldehyde under visible-light irradiation (λ > 420 nm). The excellent performance of the PANI/Bi2WO6 film could be attributed to the rapid separation and slow recombination of the photogenerated electron-hole pairs contributed by the synergic effect between PANI and Bi2WO6. The stability of the photocatalytic film is found to be satisfying, which makes it potential in practical application. This work not only solves the separation and recycling problem for nano-sized photocatalyst, but also provides insight into the design of photocatalytic film with high activity for environmental applications, especially for indoor air purification.
