Preparation, characterization, and photocatalytic activity of porous AgBr@Ag and AgBrI@Ag plasmonic photocatalysts

- Porous AgBrI@Ag photocatalysts were synthesized by a multistep route.
- The porous AgBrI@Ag showed higher activity than porous AgBr@Ag and cubic AgBr@Ag.
- The optimal I dosage in porous AgBrI@Ag for obtaining the highest photocatalytic activity is 10 at.%.
- The porous AgBrI@Ag was proved to be stable during MO recycle degradation.
