Specific Capacitance\nEnhancement of Metal–Organic\nFramework (MOF) by Boosting Intramolecular Charge Transfer Mechanism

Energy storage is very important for the forthcoming\nfuture; hence,\nthe overview of innovative materials in this research area is necessary.\nHere, two metal–organic framework (MOF) materials are described\nthoroughly, which is highly required because few MOFs are available\nonly on high-performance supercapacitors. The melamine-, manganese-,\nand molybdenum-based MOF materials, such as Me-Mn-MOFs and Me-Mo-MOFs,\nwere prepared and applied for supercapacitor applications. The MOF\nmaterials are validated and characterized using conventional characterization\nprocedures. The physicochemical properties of the materials were analyzed\nthrough sophisticated instrumental analysis. The surface morphological\nresults reveal that the melamine and manganese-based MOFs (Me-Mn-MOFs)\ndisplay a cubic-like structure, whereas the melamine and molybdenum-based\nMOFs (Me-Mo-MOFs) portray rod-like structures. The P-XRD, XPS, and\nBET results confirm the formation of the MOF materials from the starting\nmaterials. The electrochemical analysis reveals that the prepared\nmaterials could be a potential material for high-performance supercapacitor\napplications. The specific capacitances of Me-Mn-MOFs and Me-Mo-MOFs\nare 653.54 and 312.63 F/g. The asymmetric devices demonstrate that\nthe power densities of Me-Mn-MOFs and Me-Mo-MOFs are 3048.7 and 2376.6\nW/kg. The suggested materials could provide an original viewpoint\non MOFs for use in high-performance supercapacitor applications.
