Synthesis and characterization of fluorinated anatase nanoparticles and subsequent N-doping for efficient visible light activated photocatalysis.

•Synthesis of fluorinated anatase nanoparticles obtained by precipitation from solution.•Fluorinated and N co-doped anatase TiO2 obtained by wet milling process.•N-doping atoms mainly located in interstitial position.•TiO2 photocatalysts used for efficient the visible light bacterial inactivation.•Significant degree of aggregation is the limiting factor in its photocatalytic activity.
