Abstract

In this article, we report a scalable one-step synthesis of Ni@reduced graphene oxide (rGO) termed as (NGC) nanocomposites generated via synchronous reduction reaction of GO and Ni2+ ions in hydrazine hydrate solution under hydrothermal conditions, which was characterized by transmission electron microscopy, high-resolution transmission electron microscopy, Fourier transform infrared, X-ray diffraction, X-ray photoelectron spectroscopy and MH measurement. NGC nanocomposites exhibits ferromagnetic behavior with enhanced coercivity in comparison with bulk nickel, as well as superior rechargeable stability as electrode materials in supercapacitors.
