The prepared catalyst was well characterized by UV-vis, XRD, Raman, HRTEM and XPS. The synthesized composite was utilised for p-NP degradation, E. coli disinfection and H2 generation under visible light. The Sr2+/Ag-TiO2@rGO catalyst showed enhanced photocatalytic H2 evolution rate (64.3 μmol h-1) compared with Ag-TiO2@rGO (30.1 μmol h-1) and TiO2 (no activity). Nearly complete degradation of 15 mg l-1 p-NP was achieved over Sr2+/Ag-TiO2@rGO after 3 h, while only 66% and 5% RSC advancesA novel multifunctional Ag and Sr2+ co-doped TiO2@rGO ternary nanocomposite with enhanced p-nitrophenol degradation, and bactericidal and hydrogen evolution activity.PMC9085905515021061808085ME133Cao JFang FWei XfalseA novel multifunctional Ag and Sr2+ co-doped TiO2@rGO ternary nanocomposite with enhanced p-nitrophenol degradation, and bactericidal and hydrogen evolution activity.In the present study, a novel multifunctional Sr2+/Ag-TiO2@rGO ternary hybrid photocatalyst was prepared via facile sol-gel and hydrothermal methods.
