Co2 decomposition via oxygen deficient ferrite electrodes using solid oxide electrolyser cell

Abstract

Oxygen Deficient Ferrites (ODF) electrodes integrated with Yttria Stabilized Zirconia (YSZ) electrolyte, electrochemically decompose carbon dioxide (CO 2 ) into carbon (C)/carbon monoxide (CO) and oxygen (O 2 ) in a continuous process. The ODF electrodes can be kept active by applying a small potential bias across the electrodes. CO 2 and water (H 2 O) can also be electrolyzed simultaneously to produce syngas (H 2 +CO) and O 2 continuously that can be fed back to the oxy-fuel combustion. With this approach, CO 2 can be transformed into a valuable fuel source allowing CO 2 neutral use of the hydrocarbon fuels.

1 . A method to decompose CO 2  into C/CO and O 2  using Oxygen Deficient Ferrites (M x Fe 3-x O 4-δ , M represents a bivalent metal ion such as Fe(II), Cu(II), Co(II), Mn(II), Ni(II), and so on) electrodes integrated with solid oxide electrolyser cell.
