Abstract
The iron-based metal–organic frame (Fe-MOF), VNU-20, and its carbonized analogues were synthesized. Subsequently, this material was investigated for electrical properties in comparison with the carbonized samples from other MOFs and ZIFs (such as ZIF-8, ZIF-67, MOF-199, MIL-53). The experiments showed the results with the reversible cyclic voltammetry (CV) curve characterized by the redox oxidation reactions of Fe(II)/Fe(III). Furthermore, the electrode composed of carbonized VNU-20 shows a comparable capacitance with that of carbonized ZIF-67, the highest capacitance material recorded up to date for the same class of materials. While further experiments need to be carried out for the optimization, initial analyzes show the promising result for further investigation and use of carbonized VNU-20 as the electrode material for electro-catalysis and the supercapacitor.
