Abstract

We report a facile synthesis of the core/shell-like NiCo₂O₄ decorated-multiwall carbon nanotubes (MWCNTs) prepared by a dry synthesis technique and its supercapacitive property. The synthesized NiCo₂O₄/MWCNTs were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and selected area energy dispersive spectrum. The electrochemical performances of NiCo₂O₄/MWCNTs were analyzed by cyclic voltammetry. The NiCo₂O₄ nanoparticles with the average size of 6±2 nm was formed on the surface of MWCNTs to produce the core/shell-like nanostructures. The NiCo₂O₄-decorated MWCNTs electrode exhibited a maximum specific capacitance of 822 F g^-1 at a scan rate of 5.0 mV/s.
