Photodegradation of contaminants using Ag@AgCl/rGO assemblages: Possibilities and limitations

- Graphene oxide continuously reduced during formic acid degradation.
- AgCl continuously reduced to Ag metal leading to lower photocatalytic activity.
- Degradation rate impacted by both formic acid and Ag@AgCl/rGO concentration.
- HOCl is generated during irradiation, but not HO or H2O2.
- Ag@AgCl/rGO continuously degrades under irradiation leading to inactivation.
