Electrochemical Preparation of CuBi2O4 Nanoparticles on Nanoporous Stainless Steel as a Binder-Free Supercapacitor Electrode, 349. Ali A. Ensafi, N. Ahmadi and B. Rezaei ,J. Alloys & Compounds, 2015, 652, 39-47.

In this work, copper-bismuth oxide (CuBi2O4) nanoparticles were supported on nanoporous stainless
steel by a simple electrochemical deposition method and then was employed as a binder-free electrode
for supercapacitor application. The structure and surface morphologies of the nanoparticles-supported
on nanoporous stainless steel were investigated using X-ray diffraction spectroscopy, energy disper-
sive X-ray spectroscopy and scanning electron microscopy. The electrochemical properties of the pro-
posed   electrode   were   examined   using   cyclic   voltammetry   and   galvanostatic   chargeedischarge
techniques  in  different  electrolytes.  The  results  showed  that  the  proposed  electrode  exhibited  a
maximum  specific  capacitance  of  144  mA  h  g 1 or  647  F  g1 at  a  current  density  of  1.0  A  g1
in 6.0 mol L1 KOH with excellent long-term cycling stability (80% capacitance remained after 500 charge
edischarge cycles). The proposed nanostructure is a suitable candidate for electrode material in energy
storage devices.
