Nano Ag@AgBr surface-sensitized Bi2WO6 photocatalyst: oil-in-water synthesis and enhanced photocatalytic degradation

- The plasmatic Ag@AgBr surface-sensitized Bi2WO6 composite photocatalysts.
- Ag@AgBr greatly increased visible-light absorption for Bi2WO6.
- The plasmonic photocatalysts exhibited enhanced activity for the degradation of MB, phenol and salicylic acid.
