Title: Method for carbon dioxide splitting

Abstract

A method for splitting carbon dioxide via a two-step metal oxide thermochemical cycle by heating a metal oxide compound selected from an iron oxide material of the general formula A.sub.xFe.sub.3-xO.sub.4, where 0.ltoreq.x.ltoreq.1 and A is a metal selected from Mg, Cu, Zn, Ni, Co, and Mn, or a ceria oxide compound of the general formula M.sub.aCe.sub.bO.sub.c, where 0<1, 0<1, and 0<2, where M is a metal selected from the group consisting of at least one of a rare earth metal and an alkaline earth metal, to a temperature greater than approximately 1400.degree. C., thereby producing a first solid-gas mixture, adding carbon dioxide, and heating to a temperature less than approximately 1400 C, thereby producing carbon monoxide gas and the original metal oxide compound.
