Carbon dots conjugated nanocomposite for the enhanced electrochemical performance of supercapacitor electrodes.

ABSTRACT: Naturally, a combination of metal oxides and carbon materials enhances the electrochemical performance of supercapacitor (SC) electrodes. We report on two different materials with highly conductive carbon dots (CDs) and a Co_0.5Ni_0.5Fe₂O₄/SiO₂/TiO₂ nanocomposite with a high power density, a high specific surface area, and a nanoporous structure to improve power and energy density in energy storage devices. A simple and low-cost process for synthesizing the hybrid SC electrode material Co_0.5Ni_0.5Fe₂O₄/SiO₂/TiO₂/CDs, known as CDs-nanocomposite, was performed via a layer-by-layer method; then, the CDs-nanocomposite was loaded on a nickel foam substrate for
