P/Ag/Ag2O/Ag3PO4/TiO2 film showed great photocatalytic ability and stability.
107 CFU/mL of E. coli could be completely inactivated by this film within 5 min.
Photo-generated holes and O2class="glyphImg imgLazyJSB">− radicals were the major reactive species.
This photocatalyst film could be a promising candidate for bacterial disinfection.
