Investigation of synergistic effect of microwave assisted MoO3 loaded V2O5 nanocomposites for electrochemical supercapacitor

pacitor
electrode material. The novelty of the study is that the MoO₃/V₂O₅ heterostructured nanocomposites have been
fabricated in a very short time using microwave radiation and their synergistic electrochemical activity in acidic and
alkaline electrolytes investigated. The structural studies confirmed the presence of both V₂O₅ and MoO₃, and the FESEM
studies showed that the morphology of powder changes from a lamellar sheet to a nanorod-like shape when MoO₃ is added
to V₂O₅. The electrochemical performance of the prepared samples were studied for the nanocomposite of MoO₃ loaded
on V₂O₅ with specific capacitances of 224 F g⁻¹ and 172 F g⁻¹, respectively, in 1 M H₂SO₄ and 3.5 M KOH electrolytes
at 1 A g⁻¹. The synergic effect of MoO₃ and V₂O₅ gives better performance due to better charge transfer and ion diffusion.
The optimized electrode showed good electrochemical stability with 71% capacitance remaining after 5000 chargedischarge
cycles. In addition, energy density and power density values were estimated and presented for the synthesized
nanocomposites, which demonstrated the prospects of the nanocomposites in the field of electrochemical energy storage.
