This work reports on cupric oxide (CuO) nanoparticles (NPs) and cuprous oxide (Cu2O) NPs synthesized using facile green sonochemical method. Phase analysis, morphology, and crystallinity of the prepared NPs were investigated using X-ray diffraction (XRD), Fourier transform infrared (FTIR), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDS), and UV-visible diffuse reflectance spectroscopy(DRS). The phase of NPs was tuned as a function of reducing agents. XRD patterns confirmed the presence of pure CuO NPs and Cu2O NPs.  FTIR peak at 621 cm-1 confirmed Cu(I)-O vibrations, while CuO vibrations confirmed by the presence of two peaks at 536 and 586 cm-1. The FE-SEM results showed that the morphology of the CuO NPs and Cu2O NPs was highly uniform. EDS confirmed the elemental composition of Cu and O in both CuO NPs and Cu2O NPs.
