Transition metal oxides can be performant electrode materials for supercapacitors and alcohol oxidation if their conductivity and capacity are improved. Herein, an advanced nanocomposite material made of NiO‐Co 3 O 4 on reduced graphene oxide (rGO) is synthesized by a one‐step hydrothermal method for supercapacitors and methanol/ethanol oxidation. It is demonstrated that the nanocomposite is a promising material for energy storage as NiO‐Co 3 O 4 ‐rGO supercapacitor electrodes achieve a specific capacity of 149 mAh g −1 (894 F g −1 ) at a current density of 0.5 A g −1 , the discharge time of 689 s, and excellent stability of 95% after 6000 cycles. Moreover, NiO‐Co 3 O 4 ‐rGO shows a current density of 15 and 10 mA cm −2 in methanol and ethanol oxidation reactions, respectively, along with excellent stability.
