Dependence of metallic Ag on the photocatalytic activity and photoinduced stability of Ag/AgCl photocatalyst

- Ag/AgCl photocatalysts with different amounts of metallic Ag were prepared.
- Metallic Ag has a great effect on the stability and photoactivity of Ag/AgCl.
- The stable performance is due to the formation of stable Ag-AgCl structure.
