Bi2WO6/PANI: An efficient visible-light-induced photocatalytic composite

- Bi2WO6 film prepared by a CBD method was modified by PANI through in situ polymerization.
- The PANI/Bi2WO6 film exhibited excellent performance in photocatalysis.
- The enhanced photocatalytic activity was contributed by the synergic effect between PANI and Bi2WO6.
- The recombination opportunity of the photogenerated electron-hole was suppressed.
