Question
Write a note about nano catalyst.
✓
Answer
- Nano materials such as metallic nano particles, metal oxide are used as catalyst in many chemical transformation.
- Nano catalysts carry the advantages of both homogeneous and heterogeneous catalysis.
- Like homogeneous catalyst the nino catalyst give 100% selective transformations and excellent yield and show extremely high reactivity.
- Like the heterogeneous catalyst, nano catalysts can be recovered and recycled.
- Nano catalysts are actually soluble heterogeneous catalyst.
