摘要

A series of microwave-assisted MoO₃ loaded V₂O₅ nanocomposites was prepared and tested as electrochemical supercapacitor 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 charge-discharge 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.
