1. Nano materials such as metallic nano particles, metal oxide are used as catalyst in many chemical transformation.
2. Nano catalysts carry the advantages of both homogeneous and heterogeneous catalysis.
3. Like homogeneous catalyst the nino catalyst give 100% selective transformations and excellent yield and show extremely high reactivity.
4. Like the heterogeneous catalyst, nano catalysts can be recovered and recycled.
5. Nano catalysts are actually soluble heterogeneous catalyst.
