Reduction of copper salt by sodium citrate/SFS and myristic acid/SFS leads to phase pure
Cu nanoparticles. However, a similar reaction with hydrazine hydrate (HH) and sodium
formaldehyde sulfoxylate (SFS) in polymer afforded only a mixture of Cu2O and Cu. Copper
nanoparticles so-prepared were characterized by UV–Visible spectroscopy, X-ray diffraction
measurements (XRD), scanning electron microscopy (SEM) and transmission electron
microscopy (TEM). Freshly prepared solutions showed an absorption band at about 600 nm …

The applications of nanoparticles are in biological Nano sensors, optoelectronics, Nano
devices, Nano electronics, information storage, catalysis and Nano fluids which differ
significantly from size to size of nanoparticles. But controlling the size and preparation in
bulk of nanoparticles eco-friendly is interesting. This paper reports on preparation of Cu
nanoparticles by wet milling using a planetary ball mill, taking the combination of two
different sizes of balls. The milled powder is characterized using X-ray diffraction (XRD) and …
