Effects of Inorganic Stabilizers on the Formation of Copper Nanoparticles by Reduction of Copper (II) Ions with Sodium Borohydride Solutions
The process of copper (II) sulfate reduction by sodium borohydride with inorganic stabilizers (sodium citrate, sodium nitrate, sodium aminoacetate, KCl, KClO3, KBr, KBrO3, KI, KIO3) was investigated. The effect of reaction conditions (copper salt and sodium borohydride concentrations, their molar ratio, pH, temperature) on the formation copper nanoparticles, its yield and stability in aqueous solution were examined for system Cu  2+  -NaBH4-KIO3. The products were studied by UV-vis spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy.
