Abstract

The growing need for energy storing and visible light active materials has made ferroelectric materials an attractive option for the same. Bismuth ferrite is an example of such material which meet these two requirements. Bismuth ferrite was prepared through sol-gel synthesis route and the crystallinity was confirmed with X-ray diffraction (XRD) and high resolution-transmission electron microscopy (HR-TEM). The crystallite size was found to be 18 nm and the grain size found from the field emission-scanning electron microscopy (FE-SEM) was 467 nm. The optical measurement showed a band gap of 2.11 eV for the prepared sample and the low band gap has its benefit in visible light applications. The polarization study reveals the ferroelectric nature of the material and from the data the recoverable energy storage was calculated to be 1.68 mJ/cm3. The surface area studies show 1.470 m² of surface available for per gram of the prepared sample. The low band gap and recoverable energy storage properties makes synthesized bismuth ferrite material a suitable candidate for dual application in visible light photocatalytic and energy storage applications.
