Facile synthesis of nitrogen-doped carbon nanotubes encapsulating nickel cobalt alloys 3D networks for oxygen evolution reaction in an alkaline solution
NiCo@NCNTs was synthesized via a facile one-pot pyrolysis route. NiCo@NCNTs exhibited the excellent OER activity and approached that of IrO2. There is a synergistic effect between Ni and Co in NiCo@NCNTs.
