Hydrogen Production through Catalytic Water Splitting Using Liquid-Phase Plasma over Bismuth Ferrite Catalyst

Abstract

This study examined the H2 production characteristics from a decomposition reaction using liquid-phase plasma with a bismuth ferrite catalyst. The catalyst was prepared using a sol–gel reaction method. The physicochemical and optical properties of bismuth ferrite were analyzed. H2 production was carried out from a distilled water and aqueous methanol solution by direct irradiation via liquid-phase plasma. The catalyst absorbed visible-light over 610 nm. The measured bandgap of the bismuth ferrite was approximately 2.0 eV. The liquid-phase plasma emitted UV and visible-light simultaneously according to optical emission spectrometry. Bismuth ferrite induced a higher H2 production rate than the TiO2 photocatalyst because it responds to both UV and visible light generated from the liquid-phase plasma.

One-Pot Facile Synthesis of ZrO2-CdWO4: A Novel Nanocomposite for Hydrogen Production via Photocatalytic Water Splitting

“…H 2 production via water electrolysis or water splitting holds a clear edge over other contemporary methods since it does not emit secondary pollution [9,11,12]. Production of H 2 by the water-splitting process on the surface of the photocatalyst in the presence of light is being recognized as the most advanced and resourceful technology [12].…”

“…H 2 production via water electrolysis or water splitting holds a clear edge over other contemporary methods since it does not emit secondary pollution [9,11,12]. Production of H 2 by the water-splitting process on the surface of the photocatalyst in the presence of light is being recognized as the most advanced and resourceful technology [12]. The most commonly used materials to streamline this process are nanosized semiconductors that act as photocatalysts and prove to be promising candidates due to their unique physical and optical properties [13].…”
