CeO2-ZrO2 mixed oxide is an important component as oxygen storage material for example in the three-way catalysts. Also rhodium plays an important role to improve the reduction property of CeO2-ZrO2 mixed oxide because it can activate the reducing agent, i.e. H2. Continuous hydrothermal synthesis in supercritical water was used as a new synthesis method to obtain CeO2-ZrO2 mixed oxides with better OSC. In this study, the activity of Rh-loaded CeO2-ZrO2 mixed oxides for stoichiometric CO and NO elimination and their characteristics were investigated through physical characterizations with N2 adsorption, TPR, and O2-uptake. |
