Electrical, optical and photocatalytic properties of polyethylene glycol-assisted sol-gel synthesized Mn-doped TiO2/ZnO core-shell nanoparticles

- Reports sol-gel synthesis of Mn-TiO2/ZnO core-shell nanoparticles.
- Charge-transfer resistance of Mn-TiO2/ZnO is less than that of ZnO.
- Core-shell Mn-TiO2/ZnO is a better photocatalyst than Mn-TiO2.
