CuSO4 and EDTA were dissolved in Distilled Water. KBH4 was added to above solution as
reducing agent and then the solution was heated to reaction temperatures. After stirring at
different temperatures for certain time, the aqueous solution was spilled out and filtered. After
that the product was washed 3 times with ethanol and acetone separately, and finally dried in
vacuum drying oven.
Mechanism of reaction
Cu2+ + 2e- → Cu (Metallic copper in nm)
Overall reaction:
4CuSO4 + KBH4 + 8KOH→ 4Cu +4K2SO4 + KBO2 + 6H2O
KOH is used as alkaline medium in the experiment and EDTA is added as ingredient agent in order to avoid the formation of CuSO4 ppt. in alkaline medium Characterization: Formation of Copper Nano particle can be confirmed using tool such as SEM (scanning electron microscope), TEM (transmission electron microscope) and AFM (atomic force microscope).
APPLICATIONS:
1. Alloys.
2. Automotive.
3. Building materials.
4. Electrical material.
5. Hardware.
6. Marine material.
