CeO2-ZrO2 mixed oxide has the oxygen storage/release capacity (OSC) and is widely used as a promoter in the three-way catalyst. Also, CeO2-ZrO2 has potential applications as catalyst support due to its high surface area, thermal stability, and OSC. Rh was impregnated on CeO2-ZrO2 prepared by continuous hydrothermal synthesis in supercritical water and co-precipitation method. The activity of Rh-loaded CeO2-ZrO2 for catalytic reduction of NO by CO and their characteristics and thermal stability were investigated through physicochemical characterizations with TPR, N2 adsorption, O2-uptake, XRD, SEM, and H2/CO chemisorption. |
