Physicochemical and electrochemical characterization of carbon derived from Al- based metal organic framework

Abstract

Carbon materials derived from metal organic frameworks (MOF) have shown promising applications including energy storage and conversion, adsorption, gas storage and separation, catalysis, chemical sensing, and solid phase extraction. Here we present carbon materials derived from Al-based MOFs for use as electrodes in multivalent ion supercapacitors. Al MOFs were synthesized through complexation of fumaric acid with aluminum salts. Carbonization process of Al MOFs was followed by removal of Al2O3 via dissolving in NaOH solution. The properties of carbon materials were examined by X-ray diffraction (XRD), Thermogravimetric and Differential thermal analysis (TG/DTA), Fourier Infrared (FTIR) and Raman Spectroscopy, Particle Size Analysis (PSA), Scanning Electron Microscopy (SEM). The charge storage ability of carbon materials were examined in acidic and neutral aqueous solution using Cyclic Voltammetry at scan rates ranging from 5-500 mVs-1.
