In this study, 250 nm sized porous anatase TiO2 nanospheres (TiO2 NSPs) composed of 10 nm sized anataseTiO2 nanoparticles are obtained through a green synthetic route and their surfaces have been decoratedwith 3–4 nm sized plasmonic silver nanoparticles (AgNPs). Photoluminescence studies confirm thatthe AgNPs presence on TiO2 NSPs surface effectively inhibits the radiative charge recombination and thusfacilitates charge separation process at the Ag-TiO2 NSPs interface, causing an enhanced photocatalyticactivity. About 92% of the ceftiofur sodium (CFS) antibiotic taken initially is oxidized by Ag-TiO2 NSPsupon 90 min white light irradiation, while Ag loaded Degussa P25 TiO2 nanoparticles effects only 71%CFS oxidation. The synergistic effect given by plasmonic AgNPs and the continuous framework of anataseTiO2 NPs contributes to inhibit the electron-hole recombination in the Ag-TiO2 NSPs. Oxidation productsof CFS in different water sources and their eco-toxicity effects identified through LC-MS and microtoxbioassays,respectively, indicate that the obtained oxidation products are non-toxic compared to pureCFS. Therefore, porous Ag-TiO2 NSPs could be successfully applied in photocatalytic oxidation technologies,exploiting sunlight for the effective removal of pharmaceutical pollutants from wastewater.
