| 제목 | Synthesis of Co-Precipitated CeO2-ZrO2 Supports with High Oxygen Storage Capacity for Water-Gas Shift Reaction |
| 초록 | To produce highly active catalysts for water-gas shift (WGS) reaction, it is required to develop of the catalyst with high oxygen storage capacity (OSC) and high redox property. Ce(1-X)Zr(x)O2 catalytic system leads to improvements in oxygen storage capacity of CeO2 , redox property and structural stability. Roh et al. reported that cubic Ce0.8Zr0.2O2 supports exhibit the high oxygen storage capacity and high redox property. Thus, in this study, Ce/Zr ratio of supports has been fixed at 8/2. Variable parameters such as calcination temperature, support yield (g support/batch) and pH have been systematically changed. All the supports were prepared by co-precipitation method and characterized by XRD, TPR, BET analysis.
