Abstract:
In recent years, transition metal oxide (TMO) and metal organic frameworks (MOFs) have
become effective options for use as electrode materials in energy storage systems. Due to its
intercalation potential and effective interaction with Li ion, molybdenum oxide, a TMO material, offers interesting uses for Li-ion batteries. Unfortunately, pure Mo-oxide performs poorly in
electromedicine. By creating novel composites, their electrochemical performance is improved, and MOFs are one of the most qualified options since they serve as support substrates for
functional materials like metal oxides. By creating novel composites, their electrochemical
performance is improved, and MOFs are one of the most qualified options since they serve as
support substrates for functional materials like metal oxides. Although the shape, porosity, and
specific surface areas of these kinds of composites are largely determined by the precursors
chosen and the experimental setup. In this work, we have synthesized unique Molybdenum
oxide/ Fe-BDC-DMF nanocomposites, and their morphology, structural spectroscopy, and
electrochemical analysis are studied for optoelectronic and energy storage/conversion
applications. The Raman spectra of all the samples shows the characteristic vibrational modes of
α-MoO3 , β-MoO3 and MOF. We also calculate crystallite size of all composites through XRD
graphs by using scherrer formula and get crystallite size of 14.57,16.93,17.48 nm and observe
broader XRD peaks having high FWHM and low crystallite sizes due to disorder arrangements
of crystal. We also calculate the specific capacitance, energy density and power density through
CV curves through their particular formulas and we observe specific capacitance at various scan
rates and composites having high scan rate show less capacitance because the porous nature of
MOF is destroyed due to high scan rate. We notice the composite having greater amount of
MoO3 has more specific capacitance so we can say that this composite is best for capacitor
application as we get higher capacitance of 5000Fg
-1 which is greater than all the capacitance that
is published so far for MOF and MoO
