Structure stability of CeO2 nanoparticles and nanorods were studied for ethanol steam reforming reaction over Ir/CeO2 nanocatalysts. Characterizations of BET, XRD, HRTEM, H-2-TPR and H2O-TPD et al. were applied to analyze surface areas, sizes, morphologies, redox properties and water activation of the nanocatalysts. Performance results revealed that reaction patterns of ethanol steam reforming reaction were dependent on the structures of CeO2 supports, originating from different abilities in water activation. After long time stability tests conducted at high temperature of 923 K, the CeO2 nanoparticles maintained original polyhedral shape, while the CeO2 nanorods changed to polyhedrons. The shape variation of the nanorods was supposed to associated with OH groups combination and oxygen exchange in surface crystal planes of ceria nanorods, which diminished oxygen vacancies and reconstructed ceria morphology.
