Production Method of Copper Nanoparticles

Chemical Reduction Method

• Reagent Preparation: Prepare a copper salt solution, such as copper sulfate solution, and select a suitable reducing agent like sodium borohydride or hydrazine hydrate.
• Reaction: Add the reducing agent to the copper salt solution under stirring. The reducing agent reduces copper ions to form copper nanoparticles. The reaction temperature and time are usually controlled at 25 – 60°C and 1 – 3 hours respectively.
• Separation and Washing: Separate the obtained copper nanoparticles by centrifugation and wash them with deionized water and ethanol to remove impurities.

Physical Vapor Deposition

• Vaporization: Heat copper in a high – vacuum chamber to vaporize it.
• Nucleation and Growth: The copper vapor comes into contact with a cold substrate. Copper atoms nucleate and grow on the substrate surface to form copper nanoparticles. The vacuum degree is typically around 10−4 to 10−6 Pa, and the substrate temperature is 100 – 300°C.

Sol – Gel Method

• Sol Preparation: Mix copper alkoxide or other copper precursors with solvents and catalysts to form a sol.
• Gelation: Through hydrolysis and condensation reactions, the sol transforms into a gel.
• Reduction and Calcination: Reduce and calcine the gel at 300 – 600°C to obtain copper nanoparticles.
