Abstract
The present invention is directed to a method of thermochemical forming H, O, or a combination thereof from water, said method comprising the steps of contacting a composition comprising a spinel-type transition metal oxide of formula MOwith an alkali metal carbonate bicarbonate, or mixture thereof in the presence of HO to form H, CO, and an alkali metal ion-transition metal oxide; hydrolytically extracting at least a portion of alkali metal ions from the alkali metal ion-transition metal oxide by the reaction with COand liquid HO; and thermochemically reducing the resulting oxidized-transition metal oxide. The thermochemical reduction of CObased on analogous methods is also disclosed.
