CuNPs have obtained from reducing of CuSO 4 ·5H 2 O by aniline in aqueous or ethylene glycol media via chemical reduction method. Since the copper in CuSO 4 ·5H 2 O salt has valence of II and aniline can lose one hydrogen atom, the amount of aniline as reducing agent was selected twice of CuSO 4 by mole. Upon the injection of aniline into …
