In the subsequent exothermic oxidation step at 700-1200 °C, the reduced ceria was stoichiometrically reoxidized with CO2 and/or H2O to generate CO and/or H2. Each of these half-reactions is balanced separately and then combined to give the balanced redox equation. The species that is oxidized, H2(g), is the reducing agent, and the species that is reduced, CO2(g), is the oxidizing agent. Zn is oxidized to Zn2+ while H+ is reduced to H2.
