RE/ZrO2 (REÂ =Â Sm, Eu) composite oxide nano-materials: Synthesis and applications in photocatalysis

- RE/ZrO2 (RE = Sm, Eu) nano-materials have been successfully synthesized.
- Defect and electron structures determine the absorption properties on visible light.
- Nano-sized Zr0.8Sm0.2O2−δ has good visible-light-responsive photocatalytic activities.
- In the future, it can be used in wastewater treatment and environmental protection.
