要約(日本語): This work presented the synthesis and supercapacitor performance of cobalt oxide-nickel oxide (CoO-NiO) microflowers mixed with reduced graphene oxide (rGO) sheets. The hybrid material (CoO-NiO/rGO), pristine CoO-NiO and pristine rGO samples were characterized and well-confirmed by a several techniques, such as, XRD, FT-IR, SEM and EDS. Moreover, the supercapacitive properties of all samples were also studied using a electrochemical measurement technique. The results revealed that CoO-NiO/rGO (2762 F.g-1) sample exhibited much higher specific capacitance than those of the pristine CoO-NiO (1749 F.g-1) and rGO (350 F.g-1), respectively. Hence, this work indicates that the supercapacitor performance of CoO-NiO mixed with rGO hybrid materials is more superior to the pristine CoO-NiO microflowers and rGO sheets.
