A recyclable photocatalytic film of TaON/Ni foam with ohmic junction is prepared by the electrophoretic deposition technology. The photocatalytic film of 60 mg TaON/Ni foam demonstrates excellent photocatalytic activity and recycling performance for the degradation of basic fuchsin from water. Around 80% of basic fuchsin (50 mL, 10 mg L−1) is removed over 60 mg TaON/Ni foam under irradiation of 72 W LED white light for 5 h. The photocatalytic activity of the film does not significantly decrease after three rounds of use. The active species for the photocatalytic degradation of basic fuchsin are ·O2−, h+ and ·OH.
