文摘
- •
ILs-assisted solvothermal synthesis favors TiO2 spheres formation.
- •
TiO2 spheres are secured by ILs due to electrostatic and coordination interaction.
- •
TiO2 growth is limited by molecular volume of adsorbed ILs (steric hindrance).
- •
Shorter hydrocarbon chain-IL cause formation of TiO2 with increased photoactivity.
- •
