Multifunctional graphene oxide-TiO2-Ag nanocomposites for high performance water disinfection and decontamination under solar irradiation

- Multifunctional nanocomposites (GO-TiO2-Ag) was synthesized by a two-phase method.
- Remarkably enhanced photocatalytic activities were demonstrated under solar irradiation.
- Excellent intrinsic antibacterial activity and better photo-biocidal capability toward Escherichia coli.
- The influence of Ag content was revealed with systematical studies.
- Different mechanisms for enhanced photocatlytic activities were illustrated clearly.
