Synthesis and photocatalytic activity of ytterbium-doped titania/diatomite composite photocatalysts

- Yb-doped TiO2/diatomite composite photocatalysts were prepared by a sol-gel method.
- Yb-doped TiO2/diatomite photocatalysts show much higher photocatalytic activity.
- The higher photodegradation rate is due to the effect of diatomite and Yb doping.
