“…Most studies on supercapacitor electrodes focus on porous carbon materials, such as graphene, carbon nanotubes (CNTs), or carbon nanofibers (CNFs) [ 56 , 57 , 58 , 59 , 60 ]. However, these are based on electrochemical double-layer capacitances with electrostatic charge storage at the interface between electrodes and electrolytes, showing limited specific capacitances and energy densities.…”

Metal–organic frameworks (MOFs) are porous materials assembled using metal and organic linkers, showing a high specific surface area and a tunable pore size. Large portions of metal open sites in MOFs can be exposed to electrolyte ions, meaning they have high potential to be used as electrode materials in energy storage devices such as supercapacitors. Also, they can be easily converted into porous metal oxides by heat treatment. In this study, we obtained high energy storage performance by preparing electrode materials through applying heat treatment to manganese MOFs (Mn-MOFs) under air. The chemical and structural properties of synthesized and thermally treated Mn-MOFs were measured by Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM). The surface area and porosity were investigated by nitrogen adsorption/desorption isotherms. The electrochemical properties were studied by cyclic voltammetry (CV) and galvanostatic charge–discharge (GCD) using a three-electrode cell. It was found that Mn-MOF electrodes that underwent heat treatment at 400 °C under air consisted of Mn2O3 with high specific surface area and porosity. They also showed a superior specific capacitance of 214.0 F g−1 and an energy density value of 29.7 Wh kg−1 (at 0.1 A g−1) compared to non-treated Mn-MOFs.
