▎ 摘  要

The recent advances in nanotechnology developing cost-effective, high efficient catalyst for oxygen reduction reaction (ORR). In this paper, we successfully prepared the self- assembled nickel anchored reduced graphene oxide (Ni@RGO) hybrids by in situ reduction method. The formation and structural analysis of the Ni@RGO were carried out by using powder x-ray diffraction (XRD) and Raman spectroscopy. Surface morphology and topography of Ni@RGO hybrids elucidated by scanning electron microscope (SEM) and transmission electron microscope (TEM) analysis. ORR is employed in a non-aqueous electrolyte by using cyclic voltammetry and rotating disk electrode (RDE) technique. The catalytic performances of the Ni@RGO hybrids investigated in non-aqueous Li-O-2 cells and it's subjected to charge-discharge cycling at several current densities. The performance of the Ni@RGO hybrids show that, it is a potential candidate for ORR and also the catalyst for multifunctional applications.
