Copper Nanoparticles Synthesized by Chemical Reduction

Using alkylphenol ethoxylates as the modification agent, nanosized copper particles were prepared from the solution of copper sulfate with hydrazine by reductive reaction in water and methanol-water system. The stability effects and radius of nanocopper particles in various conditions of reaction were studied by TEM, XRD, FTIR The results show that the alkylphenol ethoxylates could lead to the formation of compact absorbed layer, which could improve the stability and obtain small radius of nanocopper particles when the ratio of the concentration of alkylphenol ethoxylates to copper sulfate was unit.
