Similar to other metal oxide thermochemical cycles, the cerium–cerium oxide cycle consists of two steps. The first reaction is the reduction of ceria (CeO2) to form cerium (III) oxide: [] 2 CeO 2 → Ce 2 O 3 + 1 2 O 2. In this reduction step, ceria is thermally dissociated during an endothermic reaction, generally at above 1400°C.
