Abstract Scope The development of simple and lightweight super-capacitors are considered to be an important part of next-generation energy storage applications due to low cost which shows high performance. The composites related to transition metal oxide with graphene quantum dots are considered to be suitable materials to make an improvement for the electrochemical properties in order to overcome the limitation of super-capacitor applications. In this paper, a facile hydrothermal method was used to prepare GQDs/MnCo2O4 nano-composites with improved conductivity as a promising electrode material to achieve high energy density. The synthesized materials were characterized by Fourier Transform Infra-Red (FT-IR) Spectroscopy, High-Resolution Transmission Electron Microscope (HRTEM), and Powdered X-Ray diffraction (PXRD), and BET. The specific capacitance of the fabricated composite MnCo2O4/GQDs is found to be higher than GQDs due to enhancement in electrical conductivity and diffusion of ions between electrodes and electrolyte (0.1M KOH).
