Background Solar thermochemical carbon dioxide (CO2) splitting is a process where solar energy is used to split CO2 into carbon monoxide (CO) and oxygen (O2). Conventional solar thermochemical CO2 splitting involves a metal oxide being heated to its reduction temperature using concentrated thermal energy, which liberates O2. This process also exposes...

Background Oxygen (O2) sorption materials can be used as a means for either producing a low partial pressure of oxygen (PO2) environment for chemical processes or in the production of O2 rich gas (>21 %) from leaner O2 gas streams (O2 composition < 21% down to PO2 < 10 Pa or lower). Oxygen removal and O2 enrichment are critical processes in...
