BiVO4 nanoparticles (NPs) were prepared sol-gel technique for the potential electrode of supercapacitor applications. The crystal structure, elemental composition, and surface morphology of the synthesized sample were characterized by powder X-ray diffraction (PXRD), scanning electron microscopy and elemental analysis (EDS) spectrum, respectively. The diffraction peaks were well indexed with monoclinic structure. The morphology of the synthesized sample exhibited that small flattened rice shaped structure with the average particle size of ~50 nm. The room temperature capacitive behaviour of BiVO4 NPs electrode was recorded by cyclic voltammetry (CV) in 2 M of KOH electrolyte. The enhance specific capacitance (CSP= 139 F g-1 ) was observed at the scan rate of ~10 mVs-1 . The results show that the as synthesized BiVO4 NPs is a potential candidate for electrochemical supercapacitor application.
