The effect of solvent in the sol-gel synthesis of visible light-activated, sulfur-doped TiO2 nanostructured porous films for water treatment

- Effects of solvent on the sol-gel synthesis of sulfur-doped TiO2 films were studied.
- The morphological properties of films were tailor-designed by different solvents.
- Negligible solvent effects on the sulfur doping of TiO2 were observed.
- Enhanced photocatalytic activity was achieved by judicious choice of main solvents.
