[Display omitted] •The MWCNTS-fluorine-co-doped TiO2 was synthesized by solid state method.•This MWCNTS-fluorine-co-doped TiO2 exhibited higher UV light absorption.•The MWCNTS-fluorine shows higher antimicrobial activity.•Moreover, the MWCNTS-fluorine exhibits excellent photocatalytic stability. Multi-walled carbon nanotubes-fluorine-co-doped TiO2 composite was synthesized by the solid state method. The prepared photocatalysts were characterized by using XRD, FTIR and FE-SEM. In addition, the samples were evaluated for antimicrobial activity and photocatalytic activity. The composites exhibited enhanced absorption properties in the UV light range compared to pure TiO2. The MWCNTS-F-co-doped TiO2 composites showed significant photocatalytic activity in the generation of oxygen.
