Sol-Gel Production of Unmodified and Lanthanum-Modified BiFeO3 Nanomaterials and Photoelectrochemical Studies of Hydrogen Evolution

Abstract

We provide a simple sol-gel method for synthesising LaxBi1-xFeO3 (x=0.00, 0.10). Greater control over the BiFeO3 particle shape and phase purity is possible with this manufacturing technique.X-ray diffraction, scanning electron microscopy, and UV-visible spectroscopy were used, respectively, to assess the crystallographic analysis, particle shape, and optical qualities of the material. The X-ray diffraction method proved the production of a pure phase of BiFeO3.The synthesised materials shown good photocatalytic activity when exposed to UV-visible light. We discovered that doped materials had better photocatalytic activity of producing hydrogen than virgin materials. We have also recorded the amount of hydrogen production by inverted burette technique.
