Özet

In today's technology, carbon-containing materials with high surface area and porous structure have been used extensively in energy, environment and catalysis fields.

In this study, two-dimensional graphene layers were electrochemically exfoliated from graphite rod in NaC12H25SO4 and Na2SO4 electrolyte. Ni foam was hydrothermally treated for 36 hours at 200 οC in graphene ink liquids obtained from different filtration processes. The structure and morphology of the graphene/Ni foam was investigated by SEM, Raman and BET techniques.

Graphene / Ni foam was used directly as a supercapacitor electrode, without the need for any binder or conductive material. Electrochemical performance of that was investigated by cyclic voltammetry, galvanostatic charge-discharge, and impedance spectroscopy techniques.
