Development of pristine and Au-decorated Bi₂O₃/Bi₂WO₆ nanocomposites for supercapacitor electrodes.

ABSTRACT: Pristine and Au-decorated Bi₂O₃/Bi₂WO₆ nanocomposites were synthesized via a facile hydrothermal method. Characterization techniques such as XRD, FESEM, HRTEM and XPS were used to explore the structural, morphological and electronic properties. Furthermore, electrochemical characterizations including cyclic voltammetry (CV), the galvanostatic charge-discharge (GCD) method, and electrochemical impedance spectroscopy (EIS) were performed to investigate the supercapacitance behaviour of the synthesized materials. Interestingly, the Au-decorated Bi₂O₃/Bi₂WO₆ nanocomposite showed a higher capacitance of 495.05 F g^-1 (1 M aqueous KOH electrolyte) with improved cycling stability (99.26%) over
