Abstract:

Synthesis of well dispersed copper nanoparticles was achieved by redn. of copper nitrate in aq. soln. using hydrazine monohydrate as a reducer in the presence of preformed silver nanoparticles as catalysts. It has been demonstrated that addn. of silver nanoparticles to the reaction mixt. leads to formation of aq. dispersion of copper nanoparticles and also results in a drastic redn. in reaction time compared to procedures reported in the literature. The absorption spectrum of the dispersions, HR-TEM, and STEM images and XRD pattern indicate the formation of copper nanoparticles with particle size in the range of 5-50 nm. [on SciFinder(R)]
