Production of hydrogen from water using thermal energy requires the use of reducible metal oxides at high temperatures.  In this reaction high temperatures are needed to remove oxygen, typically above 1200oC in the reduction cycle.  In the oxidation cycle the material is exposed to water vapour where hydrogen is produced and oxygen is incorporated into the lattice.  Many materials have been studied for this reaction and the most active of them are based on cerium oxide and iron oxides.  The addition of other metals or metal oxides to these materials has been shown to enhance their oxidation/reduction behaviour.  In this work we have prepared CeO2 with noble metals including Pt, Ru and Pt/Ru in an effort to increase the process of reduction during the oxidation/reduction cycles.  TEM analysis indicated sintering of the materials heated to 1200oC with the metals incorporated inside CeO2 crystallites.
