Abstract

The synthesis of an organic-inorganic supramolecular hybrid system has been reported, using a wet-chemical synthesis method, where the Bi₂O₃ nanoparticles are dispersed within the organic matrix. The XRD analysis showed the formation of crystalline Bi₂O₃. The XPS and Raman spectra analysis also confirmed the formation of Bi₂O₃. In this work, the organic molecule supported nanosized Bi₂O₃ has been used as an electrode material for supercapacitor application in presence of the aqueous solution of alkaline electrolyte (1.0 mol dm⁻³ of KOH) and exhibited a specific capacitance 407 F.g⁻¹ along with the energy density value of 113 W.h.kg⁻¹ at 1 A.g⁻¹. The supramolecular system exhibited a long-term stability by retaining 89% of the initial specific capacitance value after 500 cycles at the current density of 5 A.g⁻¹.
